When searching for a free entry in either mlx4_register_vlan() or

On a busy network, the macb driver could get stuck in the interrupt
handler, quickly triggering the watchdog, due to a confluence of
factors:
1. macb_poll re-enables interrupts unconditionally, even when it will
be called again because it exhausted its rx budget
2. macb_interrupt only disables interrupts after scheduling
macb_poll, but scheduling fails when macb_poll is already scheduled
because it didn't call napi_complete
3. macb_interrupt loops until the interrupt status register is clear,
which will never happen in this case if the driver doesn't disable
the RX interrupt
Since macb_interrupt runs in interrupt context, this effectively locks
up the machine, triggering the hardware watchdog.
This issue was readily reproducible on a flooded network with a
modified 2.6.27.48 kernel. The same problem appears to still be in the
2.6.36-rc8 driver code, so I am submitting this patch against that
version. I have not tested this version of the patch except to make
sure the kernel compiles.

Timing issues in microcode for some devices can cause a compressed BA to
be sent to the driver prior to returning any a-MPDU notification.
Traces show RTS-CTS is exchanged and then the timer fires which causes an
empty BA to be sent which acknowledges nothing. This results in a noisy
printk. Only print the message if the bitmap is non-zero.

Since aggregation is usually triggered by tx completion, a hardware
reset (because of beacon stuck, tx hang or baseband hang) can
significantly delay the transmission of the next AMPDU (until the next
tx completion event).
Fix this by rescheduling aggregation after such a reset.

The ath9k aggregation code was already checking the rate control probe flag
to prevent starting an aggregate frame with a sampling rate. What was missing
was closing an aggregate before adding a probing frame to it.
Without that, rate control cannot have precise control over probing, which
delays using faster rates when the channel conditions improve.

This updates the initvals for the AR9003 2.2 chipsets. The initvals
are the initial register values we use for our registers upon hardware
reset. This synchs up the initvals to match what our latest recommendation
from our systems engineering team.
The description of changes in this update:
Improves ability to support very strong Rx conditions.
Enhances DFS support for AP-mode.
Improves performance of Tx carrier leak calibration.
Adds support for Japan channel 14 Tx filtering requirements.
Improves Tx power accuracy.
Impact:
Update required to address degraded throughput at very short range.
Update required for AP-mode DFS certification.
Update required to comply to IEEE Tx carrier leak specification.
May not meet expected +/- 2 dB Tx power accuracy without update.
The most important fix here would be the TX carrier leakage required
to comply with IEEE 802.11 specifications. The group of changes have
been tested all together in one release.

This patch allows IBoE traffic to be encapsulated in 802.1Q tagged
VLAN frames. The VLAN tag is encoded in the GID and derived from it
by a simple computation.
The netdev notifier callback is modified to catch VLAN device
addition/removal and the port's GID table is updated to reflect the
change, so that for each netdevice there is an entry in the GID table.
When the port's GID table is exhausted, GID entries will not be added.
Only children of the main interfaces can add to the GID table; if a
VLAN interface is added on another VLAN interface (e.g. "vconfig add
eth2.6 8"), then that interfaces will not add an entry to the GID
table.
