The flow id (scd_flow) in a compressed BA packet should match the txq_id
of the queue from which the aggregated packets were sent. However, in
some hardware like the 1000 series, sometimes the flow id is 0 for the
txq_id (10 to 19). This can cause the annoying message:
[ 2213.306191] iwlagn 0000:01:00.0: Received BA when not expected
[ 2213.310178] iwlagn 0000:01:00.0: Read index for DMA queue txq id (0),
index 5, is out of range [0-256] 7 7.
And even worse, if agg->wait_for_ba is true when the bad BA is arriving,
this can cause system hang due to NULL pointer dereference because the
code is operating in a wrong tx queue!

We are seeing some race conditions between incoming station management
requests (station add/remove) and the internal unassoc RXON command that
modifies station table. Modify these flows to require the mutex to be held
and thus serializing them.

This patch added to 2.6.34:
commit f8d1dcaf88bddc7f282722ec1fdddbcb06a72f18
Author: Jesse Brandeburg <jesse.brandeburg@intel.com>
Date: Tue Apr 27 01:37:20 2010 +0000
ixgbe: enable extremely low latency
introduced a feature where LRO (called RSC on the hardware) was disabled
automatically when setting rx-usecs to 0 via ethtool. Some might not
like the fact that LRO was disabled automatically, but I'm fine with
that. What I don't like is that LRO/RSC is automatically enabled when
rx-usecs is set >0 via ethtool.
This would certainly be a problem if the device was used for forwarding
and it was determined that the low latency wasn't needed after the
device was already forwarding. I played around with saving the state of
LRO in the driver, but it just didn't seem worthwhile and would require
a small change to dev_disable_lro() that I did not like.
This patch simply leaves LRO disabled when setting rx-usecs >0 and
requires that the user enable it again. An extra informational message
will also now appear in the log so users can understand why LRO isn't
being enabled as they expect.
Inconsistency of LRO setting first noticed by Stanislaw Gruszka.

commit 675ad47375c76a7c3be4ace9554d92cd55518ced
removed the capability to use ethtool.set_msglevel to
control the types of messages emitted by the driver.
That commit should probably be reverted.
If not, then this patch fixes a message logging defect

There is a small window where the watchdog could be running as the
interface is brought down on a NIC with two ports wired back to back.
If ixgbe_update_status is then called can lead to a panic. This patch
allows the update to bail if we are in that condition.
This issue was orignally reported and fix proposed by Akihiko Saitou.

Use struct rtnl_link_stats64 as the statistics structure.
On 32-bit architectures, insert 32 bits of padding after/before each
field of struct net_device_stats to make its layout compatible with
struct rtnl_link_stats64. Add an anonymous union in net_device; move
stats into the union and add struct rtnl_link_stats64 stats64.
Add net_device_ops::ndo_get_stats64, implementations of which will
return a pointer to struct rtnl_link_stats64. Drivers that implement
this operation must not update the structure asynchronously.
Change dev_get_stats() to call ndo_get_stats64 if available, and to
return a pointer to struct rtnl_link_stats64. Change callers of
dev_get_stats() accordingly.

If oui were a null variable then vic_provinfo_alloc() would leak memory.
But this function is only called from one place and oui is not null so
I removed the check.
I also moved the memory allocation down a line so it was easier to spot.

The point of using the devres resource management routines is that they
simplify the driver by taking care of releasing resources on failure and
release. A recent commit added a bunch of error handling that is unnecessary
in this context.
This patch removes this redundant error handling, as well as using
dmam_alloc_coherent in place of dma_alloc_coherent in order to use this
framework consistenly throughout the driver.

Since commit cc772ab7cdcaa24d1fae332d92a1602788644f7a ("gianfar: Add
hardware RX timestamping support"), the driver no longer works on
at least MPC8313ERDB and MPC8568EMDS boards (and possibly much more
boards as well).
That's how MPC8313 Reference Manual describes RCTRL_TS_ENABLE bit:
Timestamp incoming packets as padding bytes. PAL field is set
to 8 if the PAL field is programmed to less than 8. Must be set
to zero if TMR_CTRL[TE]=0.
I see that the commit above sets this bit, but it doesn't handle
TMR_CTRL. Manfred probably had this bit set by the firmware for
his boards. But obviously this isn't true for all boards in the
wild.
Also, I recall that Freescale BSPs were explicitly disabling the
timestamping because of a performance drop.
For now, the best way to deal with this is just disable the
timestamping, and later we can discuss proper device tree bindings
and implement enabling this feature via some property.

Reading the ELP_CTRL register with sdio_readb causes problems because
hardware seems to be performing a write using stuff bits in the request
(those bits contain write data in write request). This indicates that it
actually expects RAW (read after write) type of request, so perform that
when reading ELP_CTRL instead. Also cache last written value so we know
what to write when doing RAW request.
Because of the above it was not possible to wake the chip from ELP power
saving mode, PM had to be disabled to have the driver usable in SDIO
mode. After this patch PM is functional.
For backporting to 2.6.34 or earlier, this patch depends on
6c1f716e8154ee9315534782b9b1eedea0559a24, which adds the
required SDIO funcion.

Collect all pieces concering the antenna switch table into one function.
Previously it was split up between ath5k_hw_reset() and
ath5k_hw_commit_eeprom_settings().
Also we need to set the antenna switch table when ath5k_hw_set_antenna_mode()
is called manually (by "iw phy0 antenna set", for example).
I'm not sure if we need to set the switchtable at the same place in
ath5k_hw_reset() as it was before - it is set later thru
ath5k_hw_set_antenna_mode() anyways - but i leave it there to avoid
problems(?).
Plus print switchtable registers in the debugfs file.
