Since we have to be able to handle MD updates, having an in-tree
set of data structures representing the MD objects actually makes
things more painful.
The MD itself is easy to parse, and we can implement the existing
interfaces using direct parsing of the MD binary image.
The MD is now reference counted, so accesses have to now take the
form:
handle = mdesc_grab();
... operations on MD ...
mdesc_release(handle);
The only remaining issue are cases where code holds on to references
to MD property values. mdesc_get_property() returns a direct pointer
to the property value, most cases just pull in the information they
need and discard the pointer, but there are few that use the pointer
directly over a long lifetime. Those will be fixed up in a subsequent
changeset.
A preliminary handler for MD update events from domain services is
there, it is rudimentry but it works and handles all of the reference
counting. It does not check the generation number of the MDs,
and it does not generate a "add/delete" list for notification to
interesting parties about MD changes but that will be forthcoming.

For most pre-5705 devices, multiple link interrupts were being generated
for a single physical link change. The source of the interrupts was
determined to be unnecessary toggling of the MAC link polarity bit.
This patch changes the way the link polarity bit gets configured. Where
possible, code that dynamically configures the bit in response to link
changes has been replaced by code that configures the bit once during
initialization time and then leaves the bit alone.
For correctness, this patch also limits the use of the bit to those
devices where it is defined, namely devices before the 5705. This patch
also corrects the link polarity configurations for 5700 devices when
paired against a bcm5411 phy.

Gagan Arneja <gaagaan@gmail.com> pointed out that tg3_reset_task()
could potentially race with another thread calling tg3_full_lock()
such as the ethtool_set_xxx() functions. This may trigger the
BUG_ON() in tg3_irq_quiesce() or cause the irq_sync flag to be out-
of-sync.
I think the easiest way to fix this is to get the tp->lock first
before setting the irq_sync flag. This is safe to do because the
tp->lock is never grabbed by the irq handler. This change will
guarantee that the irq_sync flag updates will be serialized. We also
have to change one spot to call tg3_netif_start() (which clears the
irq_sync flag) before releasing the tp->lock.

sysfs is now completely out of driver/module lifetime game. After
deletion, a sysfs node doesn't access anything outside sysfs proper,
so there's no reason to hold onto the attribute owners. Note that
often the wrong modules were accounted for as owners leading to
accessing removed modules.
This patch kills now unnecessary attribute->owner. Note that with
this change, userland holding a sysfs node does not prevent the
backing module from being unloaded.

Instead of all drivers reading pci config space to get the revision
ID, they can now use the pci_device->revision member.
This exposes some issues where drivers where reading a word or a dword
for the revision number, and adding useless error-handling around the
read. Some drivers even just read it for no purpose of all.
In devices where the revision ID is being copied over and used in what
appears to be the equivalent of hotpath, I have left the copy code
and the cached copy as not to influence the driver's performance.

Spurious interrupts are often encountered especially on systems
using the 8259 PIC mode. This is because the I/O write to deassert
the interrupt is posted and won't get to the chip immediately. As
a result, the IRQ may remain asserted after the IRQ handler exits,
causing spurious interrupts.
Add read back to flush the I/O write to deassert the IRQ immediately.
We also store the last_status_idx immediately in the IRQ handler to
help detect whether the interrupt is ours or not when the IRQ is
entered again before ->poll gets called.

While playing with the firmware a while back, I discovered a way to
access the device's entire address space before the firmware has been
loaded.
Previously we were loading the firmware early on (during probe) so that
we could read the MAC address from the EEPROM and register a netdevice.
Now that we can read the EEPROM without having firmware, we can defer
firmware loading until later while still reading the MAC address early
on.
This has the advantage that zd1211rw can now be built into the kernel --
previously if this was the case, zd1211rw would be loaded before the
filesystem is available and firmware loading would fail.
Firmware load and other device initialization operations now happen the
first time the interface is brought up.
Some architectural changes were needed: handling of the is_zd1211b flag
was moved into the zd_usb structure, MAC address handling was obviously
changed, and a preinit_hw stage was added (the order is now: init,
preinit_hw, init_hw).

Matteo Croce reported Aironet initialization failures. They were caused by
a race in airo. airo finds a free interface name, then initializes the card
and finally registers the interface. Another device may get the same name
in the meantime.
The reason airo gets its name early is to use it in informative printks and
to name the resources it requests. The printks will be just fine without
the interface name and the resources can use the driver's name - that's
what other network drivers do anyway.
One of the talkative functions is setup_card(). It is called once before

At present, when a device is enslaved to bonding, if ipv6 is
active then addrconf will be initated on the slave (because it is closed
then opened during the enslavement processing). This causes DAD and RS
packets to be sent from the slave. These packets in turn can confuse
switches that perform ipv6 snooping, causing them to incorrectly update
their forwarding tables (if, e.g., the slave being added is an inactve
backup that won't be used right away) and direct traffic away from the
active slave to a backup slave (where the incoming packets will be
dropped).
This patch alters the behavior so that addrconf will only run on
the master device itself. I believe this is logically correct, as it
prevents slaves from having an IPv6 identity independent from the
master. This is consistent with the IPv4 behavior for bonding.
This is accomplished by (a) having bonding set IFF_SLAVE sooner
in the enslavement processing than currently occurs (before open, not
after), and (b) having ipv6 addrconf ignore UP and CHANGE events on
slave devices.
The eql driver also uses the IFF_SLAVE flag. I inspected eql,
and I believe this change is reasonable for its usage of IFF_SLAVE, but
I did not test it.

We intend this patch to improve spidernet interrupt handling to be

-when CONFIG_DEBUG_SHIRQ=y, request_irq() calls handler().
-when spider_net_open() is called, it calls request_irq() which calls
spider_net_interrupt().
-if some specific interrupt bit is set at this timing, it calls
netif_rx_schedule() and spider_net_poll() is scheduled.
-spider_net_open() calls netif_poll_enable() which clears the bit
__LINK_STATE_RX_SCHED.
-when spider_net_poll() is called, it calls netif_rx_complete() which
causes BUG_ON() because __LINK_STATE_RX_SCHED is not set.

The 3cSOHO100-TX needs a mdio_sync() before mdio_read() to read the MII
transceiver registers properly. Adding EXTRA_PREAMBLE to drv_flags of the
3cSOHO100-TX will force this.
This problem exists already for years (I checked back to 2.6.8).
Setting duplex for the 3cSOHO100-TX was more or less a random process.
Till 2.6.15 it was more likely that the diver ends up in half
duplex mode, after the code change in 2.6.16 it was more likely
to end up in full duplex mode. I wonder why nobody noticed this earier.

Due to a HW issue, our current scheme to transition the connection from

and driver now support a new transition scheme for the passive side:
- driver posts rdma_init_wr (now including the initial receive seqno)
- driver posts last streaming message via TX_DATA message (MPA start
response)
- uP atomically sends the last streaming message and transitions the
tcb to rdma mode.
- driver waits for wr_ack indicating the last streaming message was ACKed.

The rx copybreak part is straightforward.
The align field in struct rtl_cfg_info is related to the alignment
requirements of the DMA operation. Its value is set at 2 to limit the
scale of possible regression but my old v1.21 8169 datasheet claims a

The driver version number has not been updated since the driver was
included in the main kernel tree and there is no plan on updating this
in the future either. At this point, the only correct way to refer to
the version is to use the kernel version. The 0.4.4 version is
confusing since there are external version with higher version number
even though they are not actually any newer than the in-tree version.
Let's get rid of the version number in the kernel tree in order to
avoid this kind of confusion.

The vendor driver code suggests that CR47 patching happens on every channel
change for every RF (depending on bit 8 in POD).
Due to a bug in their driver (upper bits of RF_Mode get zeroed out, then
are examined for 1s when setting some other flags), this isn't actually
what happens, and their generic CCK patching routine never takes effect.
Some of their RF configurations do include explicit (duplicated) code
for CR47 patching though. This patch makes zd1211rw match that
behaviour.

This patch adds support for another radio appearing in new devices: the
Ubec UW2453. It's more complicated than the other RF's we support, but
Ubec publish full tech specs so we're able to understand the vendor code
relatively well.
Now that we support UW2453, we also support Atheros' new USB chip: the
AR5007UG. From the little info we have, this appears to be just a
rebranded ZD1211B.
This RF code doesn't work very well -- lots more TX/RX errors than the
other RFs. However, the vendor driver doesn't do any better, so this is
all we can do for now.

In 7d12e780e0 David Howells performed
this evolution:
"IRQ: Maintain regs pointer globally rather than passing to IRQ handlers"
He correctly updated many of the function definitions that were using this
extra regs pointer parameter but forgot to update some caller sites of
those functions. The reason the modifications was not properly done on all
drivers is that some drivers were rarely compiled because they are for
AMIGA, or that some code sites were inside #ifdefs where the option is not
set or inside #if 0.
Here is the semantic patch that found the occurences
and fixed the problem.
