This reverts commit 18babd3854.
Michael Barkowski points out that it's wrong, and I agree. The
patch causes a problem rather than fixes one after another
patch "ucc_geth: Fix BD processing" was applied. Before that
patch, current packet should be blocked. However after the patch
current packet is ok and we only need to block next.

Under rare conditions, the MAC might hang while generating a pause frame.
This patch fine tunes the MAC settings to avoid the issue, allows for
periodic MAC state check, and triggers a recovery if hung.

During testing of bcm43xx interference mitigation, two problems were
discovered:
(1) When the MANUALWLAN mode was set, routines _stack_save and _stack_restore
generated assertions that were traced to saving ILT registers with addresses
> 0xFFF. This problem was fixed by adding one bit to the field used for
the offset, and subtracting one bit from the space used for the id.
(2) In MANUALWLAN mode, the IRQ XMIT errors are generated. The cause of these
errors has not yet been located. Any suggestions on debugging this problem
would be greatly appreciated.

This patch fixes the poll routine for the natsemi driver so that if the
driver detects an RX state machine lockup then no interrupts will be
lost while the driver recovers from that.

The interrupt status register for the natsemi chips is clear on read and
was read unconditionally from both the interrupt and from the NAPI poll
routine, meaning that if the interrupt service routine was called (for
example, due to a shared interrupt) while a NAPI poll was scheduled
interrupts could be missed. This patch fixes that by ensuring that the
interrupt status register is only read by the interrupt handler when
interrupts are enabled from the chip.
It also reverts a workaround for this problem from the netpoll hook and
improves the trace for interrupt events.
Thanks to Sergei Shtylyov <sshtylyov@ru.mvista.com> for spotting the
issue, Mark Huth <mhuth@mvista.com> for a simpler method and Simon

The natsemi drivers include functions for enabling and disabling
interrupts from the chip but these are not used in all code paths. This
patch changes the code paths that touch the interrupt enable register to
use the functions. In all cases this adds an extra PCI read to post the
operation but since none of these are in fast paths this shouldn't be
too much of a problem.

When bonding does fail over it calls set_mac_address. When this happens
as the result of another port going down, the phy_mutex that is common to
both ports is held, so it deadlocks. Setting the address doesn't need to do
anything that needs the phy_mutex, it already has the RTNL to protect against
other admin actions.
This change just disables the receiver to avoid any hardware confusion
while address is changing.

In active-backup mode, the current bonding code duplicates IGMP
traffic to all slaves, so that switches are up to date in case of a
failover from an active to a backup interface. If bonding then fails
back to the original active interface, it is likely that the "active
slave" switch's IGMP forwarding for the port will be out of date until
some event occurs to refresh the switch (e.g., a membership query).
This patch alters the behavior of bonding to no longer flood
IGMP to all ports, and to issue IGMP JOINs to the newly active port at
the time of a failover. This insures that switches are kept up to date
for all cases.
"GOELLESCH Niels" <niels.goellesch@eurocontrol.int> originally

Bonding can erroneously register the same packet_type to receive
ARPs (for use by ARP validation): once at device open time, and once via
sysfs. Since sysfs can change the validate setting (and thus register
or unregister) at any time, a flag is needed to synchronize with device
open in order to avoid double registrations, and the simplest place is
within the packet_type structure itself. Double unregister is not an
issue.

It is based on the assumption that an interface's ifindex is basically
an alias for a local MAC address, so incoming packets now are matched
to sockets based on remote MAC, session id, and ifindex of the
interface the packet came in on/the socket was bound to by connect().
For relayed packets, the socket that's used for relaying is selected
based on destination MAC, session ID and the interface index of the
interface whose name currently matches the name requested by userspace
as the relaying source interface.

The change below seems to add back in the declaration and

the driver compile for me, although I have no hardware and hence no
way to test whether this actually works.

To reproduce this panic consistently, we run an intensive network
application like 'netperf'. After waiting for a couple of seconds,
you will see a stack trace and a kernel panic where we are calling
pci_unmap_single() in ql_poll().
Changes:
1) Check the flags on the Response MAC IO Control block to check for
errors
2) Ensure that if we are on the 4022 we only use one segment
3) Before, we were reading the memory mapped producer index register
everytime we iterated in the loop when clearing the queue. We should
only be iterating to a known point, not as the producer index

This version moves the medium variable to the card specific structure and
changes the GMII_* to BCM54XX_* #defines.
This patch adds improved version of enable_fiber for both the 5421 and
the 5461 phy. It is now possible to specify with these wether you want
autonegotiation or not. This is needed for bladecenter switches where
some expect autonegotiation and some dont seem to like this at all.
Depending on this flag it sets phy->autoneg accordingly for the fiber mode.
More importantly it implements proper read_link and poll_link functions
for both phys which can handle both copper and fiber mode by determining
the medium first and then branching to the required functions. For fiber
they all work fine, for copper they are not tested but return the result
of the genmii_* function anyway which is supposed to work.
The patch moves the genmii_* functions around to avoid foreward declarations.

incorporated into the 2.6 kernel by Jeff Morrow of Sierra Analytics, Feb
2007. <jmorrow@massspec.com>
The changes have been tested on a Contemporary Controls PCI20U-4000.
Summary of changes:
Arc-rawmode.c:
rx():
- Fixed error in received packet lengths; 256 byte packets were
being received as 257 bytes packets.
prepare_tx():
- Fixed error in transmit length calcs; 257 byte packets were being
transmitted as 260 byte packets.
com20020.c:
com20020_check():
- We now load the SETUP2 register if the 'clockm' parameter is
non-zero, instead of checking for ARC_CAN_10MBIT. The user is
now responsible for whether or not SETUP2 is loaded. If the
clock multiplier is non-zero, this means that the user wants a
baud rate greater than 2.5Mbps. This is not possible unless the
SETUP2 register is present (COM20020D, or COM20022). So, we're
relying on the user to be smart about what kind of chip he's
dealing with...
com20020-pci.c
- Added several entries to com20020pci_id_table[].

It was hardly necessary to repeat most of the code from gfar_error() in
gfar_interrupt(), especially having some inconsistencies between the two.
So, make the gfar_interrupt() just call gfar_error(), and not acknowledge
the interrupts itself as gfar_{receive/transmit/error}() do it anyway.
While at it, also clarify/cleanup debug messages in gfar_error()...

On some Asus motherboards containing the L1 NIC, the MAC address is
written by the BIOS directly to the MAC register during POST, and is
not stored in eeprom. If we don't succeed in fetching the MAC address
from eeprom or spi, try reading it directly from the MAC register.
Suggested by Xiong Huang.

Nearly all of the writes to the bcm43xx internal lookup tables (ilt)
involve 16-bit quantities. Accordingly, the ilt_write routine was
coded to pass a u16 value. For one early GPHY chip, 32-bit quantities
are needed. For those writes, the value was clipped to 16 bits. This
patch adds an ilt_write32 routine that receives a 32-bit quantity
and writes it to the appropriate locations.

Correct assignment of DOT1XENABLE in WE-19 codepaths.
RX_UNENCRYPTED_EAPOL = 1 really means setting DOT1XENABLE _off_, and
vice versa. The original WE-19 patch erroneously reversed that. This

wpa_supplicant.
It also adds two missing break statements that, left out, could result

The semantic effect of insert_at_head is that it would allow new registered
sysctl entries to override existing sysctl entries of the same name. Which is
pain for caching and the proc interface never implemented.
I have done an audit and discovered that none of the current users of
register_sysctl care as (excpet for directories) they do not register
duplicate sysctl entries.
So this patch simply removes the support for overriding existing entries in
the sys_sysctl interface since no one uses it or cares and it makes future
enhancments harder.

After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there. Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.
To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.
Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm. I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).

Many struct file_operations in the kernel can be "const". Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data. In addition it'll catch accidental writes at compile time to
these shared resources.
