This patch replaces current PowerPC 4xx EMAC driver with
new, re-written from the scratch version. This patch is quite big
(~234K) because there is virtualy 0% of common code between old and
new version.
New driver uses NAPI, it solves stability problems under heavy packet
load and low memory, corrects chip register access and fixes numerous
small bugs I don't even remember now.
This patch has been tested on all supported in 2.6 PPC 4xx boards.
It's been used in production for almost a year now on custom
4xx hardware. PPC32 specific parts are already upstream.
Patch was acked by the current EMAC driver maintainer (Matt Porter). I
will be maintaining this new version.

This patch fixes a bug that happens when the hypervisor can't add a

called BUG(). The patch writes the right value into the free_map array
so that the index can be reused.

This patch removes the allocation of RX skb's buffers from a workqueue
to be called directly at RX processing time. This change was suggested
by Dave Miller when the driver was starving the RX buffers and
deadlocking under heavy traffic:
> Allocating RX SKBs via tasklet is, IMHO, the worst way to
> do it. It is no surprise that there are starvation cases.
>
> If tasklets or work queues get delayed in any way, you lose,
> and it's very easy for a card to catch up with the driver RX'ing
> packets very fast, no matter how aggressive you make the
> replenishing. By the time you detect that you need to be
> "more aggressive" it is already too late.
> The only pseudo-reliable way is to allocate at RX processing time.

This patch changes the way the ibmveth driver handles the receive
buffers. The old code mallocs and maps all the buffers in the pools
regardless of MTU size and it also limits the number of buffer pools to
three. This patch makes the driver malloc and map the buffers necessary
to support the current MTU. It also changes the hardcoded names of the
buffer pool number, size, and elements to arrays to make it easier to
change (with the hope of making them runtime parameters in the future).

firmware will timeout and reset the device if no heartbeat is received

In PM v1, all devices were called at SUSPEND_DISABLE level. Then
all devices were called at SUSPEND_SAVE_STATE level, and finally
SUSPEND_POWER_DOWN level. However, with PM v2, to maintain
compatibility for platform devices, I arranged for the PM v2
suspend/resume callbacks to call the old PM v1 suspend/resume
callbacks three times with each level in order so that existing
drivers continued to work.
Since this is obsolete infrastructure which is no longer necessary,
we can remove it. Here's an (untested) patch to do exactly that.

This is a (final?) hack to support the odd DMA allocation requirements
of the b44 hardware. The b44 hardware has a 30-bit DMA mask. On x86,
anything less than a 32-bit DMA mask forces allocations into the 16MB
GFP_DMA range. The memory there is somewhat limited, often resulting
in an inability to initialize the b44 driver.
This hack uses streaming DMA allocation APIs in order to provide an
alternative in case the GFP_DMA allocation fails. It is somewhat ugly,
but not much worse than the similar existing hacks to support SKB
allocations in the same driver. FWIW, I have received positive
feedback on this from several Fedora users.

Get rid of the mdelay call in rhine_disable_linkmon. The function
is called from the via-rhine versions of mdio_read and mdio_write.
Those functions are indirectly called from rhine_check_media and
rhine_tx_timeout, both of which can be called in interrupt context.
So, create tx_timeout_task and check_media_task as instances of struct
work_struct inside of rhine_private. Then, change rhine_tx_timeout to
invoke schedule_work for tx_timeout_task (i.e. rhine_tx_timeout_task),
moving the work to process context. Also, change rhine_error (invoked
from rhine_interrupt) to invoke schedule_work for check_media_task
(i.e. rhine_check_media_task), which simply calls rhine_check media
in process context. Finally, add a call to flush_scheduled_work in
rhine_close to avoid any resource conflicts with pending work items.

From Suzanne Wood <suzannew@cs.pdx.edu>:
Clarify RCU implementation in bpqether.c.
Because bpq_new_device() calls list_add_rcu() and bpq_free_device() calls
list_del_rcu(), substitute list_for_each_entry_rcu() for
list_for_each_entry() in bpq_get_ax25_dev() and in bpq_seq_start().
Add rcu dereference protection in bpq_seq_next().
The rcu_read_lock()/unlock() in bpq_device_event() are removed because
netdev event handlers are called with RTNL locking in place.
FYI: bpq_free_device() calls list_del_rcu() which, per list.h, requires
synchronize_rcu() which can block or call_rcu() or call_rcu_bh() which
cannot block. Herbert Xu notes that synchronization is done here by
unregister_netdevice(). This calls synchronize_net() which in turn uses
synchronize_rcu().

This patch fixes the following bugs with offline diagnostics
code(run with "ethtool -t").
1. After running offline diagnostics, adapter would report
corrupted packets on receive. This was because of adapter not
being brought out of "RLDRAM test mode".
2. Current EEPROM test works only for Xframe I. Since Xframe II
uses different interface(SPI), support for this interface has
been added. Also, since SPI supports write access to all areas
of EEPROM, negative testing is done only for Xframe I.
3. Return values from subfunctions of offline diagnostics have
been corrected.
4. In register test, expected value from rx_queue_cfg register
is made to depend on adapter type.
5. After the test, need to restore values at EEPROM offsets
0x4F0 and 0x7F0. These locations were modified as part of test.
6. Use macro SPECIAL_REG_WRITE for write access to mc_rldram_test_ctrl
register. Also, couple of unnecessary writes to mc_rldram_test_ctrl
have been removed.

The aironet PCI driver has a build dependency on ISA that prevent the
driver to compile on systems that doesn't support ISA, like x86_64. The
driver really doesn't depend on ISA, it does some ISA stuff in the
initialization code, since the driver supports both ISA and PCI cards. So
the driver should depend on ISA_DMA_API to build on all systems, and this
will not hurt PCI at all.

Replicate IGMP frames across all slaves in activebackup mode. This

multicast traffic will be lost until the next IGMP membership report
poll timeout.
This is conceptually similar to the treatment of IGMP traffic in
bond_alb_xmit. In that case, IGMP traffic transmitted on any slave
is re-routed to the active slave in order to ensure that multicast
traffic continues to be directed to the active receiver.

Unfortunately, [your patch] might address the crash but doesn't address
the real problem. It turns out that the problem is one of padding
(the firmware cksum engine works only on 32-bit chunks, yuck), so
the special casing for length == 1 wasn't sufficient anyway.
This patch addresses the issue, as well the other issue of i386 +
CONFIG_HIGHMEM being broken. It is pretty much the same workaround
that Adaptec themselves used in their Windows driver. I have yet to
check if it fixes the problem when the skb is non-linear, but this

local->hw_priv was being freed and set to NULL just before calling
prism2_free_local_data(). However, this may expose a race condition in
which something ends up trying to use hw_priv during shutdown. I

let's postpone hw_priv freeing to happen only after
prism2_free_local_data() has returned.

Host AP driver used hardware model specific dev_open/close handlers
that were called on dev_open/close if the hardware driver had
registered the handler. These were only used for hostap_cs and only
for tracking whether any of the netdevs were UP. This information is
already available from local->num_dev_open, so there is not need for
the special open/close handler.
Let's get rid of these handlers. In addition to cleaning up the code,
this fixes a module refcounting issue for hostap_cs where ejecting the
card while any of the netdevs were open did not decrement refcount
properly.

The following patch renames __in_dev_get() to __in_dev_get_rtnl() and
introduces __in_dev_get_rcu() to cover the second case.
1) RCU with refcnt should use in_dev_get().
2) RCU without refcnt should use __in_dev_get_rcu().
3) All others must hold RTNL and use __in_dev_get_rtnl().
There is one exception in net/ipv4/route.c which is in fact a pre-existing
race condition. I've marked it as such so that we remember to fix it.

Fix 5780 PHY related problems:
1. MAC_RX_MODE reset must be done before setting up the MAC_MODE
register on 5705_PLUS chips or the chip will stop receiving after
a while. The MAC_RX_MODE reset is needed to prevent intermittently
losing the first receive packet on serdes chips.
2. Skip MAC loopback test on 5780 because of hardware errata. Normal
traffic including PHY loopback is not affected by the errata.
3. PHY loopback fails intermittently on 5708S and this is fixed by
putting the PHY in loopback mode first before programming the MAC
mode register. A MAC_RX_MODE reset is also added.
4. Return -EINVAL in tg3_nway_reset() if device is in TBI mode. Allow
nway_reset if 5780S is in parallel detect mode.

Do not count non-error frames dropped by the hardware as
part of rx_dropped. Instead, count those frames dropped as
rx_missed_errors. Also, do not count other error frames as part of
rx_dropped. Finally, do not count oversized frames in rx_dropped
(since they are counted as part of rx_length_errors).

Fix PCI device id issues with sk98lin driver.
1. DLINK 530-T card has no Vital Product Data (VPD) area so the sk98lin
driver won't work. (skge does however)
2. Remove commented out Yukon2 stuff
3. Restrict Linksys card to revisions that don't conflict with r8169 version.

A few improvements to the Freescale/ColdFire FEC driver:
. some formatting cleanups
. add support for the FEC device in the ColdFire 523x processor family
. add support for MAC address setting on MOD5272 and M5272C3 boards
. don't re-read the PHY status register many times
. ack status interrupt before reading status register
. move printing init message to after full init (so that the
ethX name is filled out for printing)

This ports the Sun GEM ROM mapping/enable fixes it sunhme (which used

This same patch was reported to fix the MAC address detection on sunhme
(next patch). Most people seem to be running this on Sparcs or PPC
machines, where we get the MAC address from their respective firmware
rather than from the (previously broken) ROM mapping routines.

This patch does a full cleanup of 'NULL checks before vfree', and a partial
cleanup of calls to kfree for all of drivers/ - the kfree bit is partial in
that I only did the files that also had vfree calls in them. The patch
also gets rid of some redundant (void *) casts of pointers being passed to
[vk]free, and a some tiny whitespace corrections also crept in.

29 July 2005, Cambridge, MA:
This afternoon Alan Stern submitted a patch to remove the URB_ASYNC_UNLINK
flag from the Linux kernel. Mr. Stern explained, "This flag is a relic
from an earlier, less-well-designed system. For over a year it hasn't
been used for anything other than printing warning messages."
An anonymous spokesman for the Linux kernel development community
commented, "This is exactly the sort of thing we see happening all the
time. As the kernel evolves, support for old techniques and old code can
be jettisoned and replaced by newer, better approaches. Proprietary
operating systems do not have the freedom or flexibility to change so
quickly."
Mr. Stern, a staff member at Harvard University's Rowland Institute who
works on Linux only as a hobby, noted that the patch (labelled as548) did
not update two files, keyspan.c and option.c, in the USB drivers' "serial"
subdirectory. "Those files need more extensive changes," he remarked.
"They examine the status field of several URBs at times when they're not
supposed to. That will need to be fixed before the URB_ASYNC_UNLINK flag
is removed."
Greg Kroah-Hartman, the kernel maintainer responsible for overseeing all
of Linux's USB drivers, did not respond to our inquiries or return our
calls. His only comment was "Applied, thanks."

Fix bug in bnx2_interrupt() that caused an unnecessary register read.
The BNX2_PCICFG_MISC_STATUS should only be read when the status tag
has not changed.
Add prefetch of the status block in bnx2_msi() similar to tg3_msi().
The status block is not touched in bnx2_msi() and prefetching it will
speed up bnx2_poll() that will run on the same CPU that received the
MSI.
Update version.

I noticed a strange return value in smsc_ircc_init in
drivers/net/irda/smsc_ircc2.c in rc4-mm1.
When reaching the line "if (ircc_fir > 0 && ircc_sir > 0)", ret is 0. So I
don't see the point of setting it to 0 in the "else" case. >From what I
see in 2.6.12 it should probably be set to -ENODEV at the begining of the
"else" case. The attached patch does this.
Note that I didn't actually see any breakage caused by this.
