This change makes it a bit easier to do the loopback frame creating and
testing. Previously we were doing an and to drop the last bit, and then
dividing the frame_size by 2 in order to get locations for frame bytes and
testing. Instead we can simplify it by just shifting the register one bit
to the right and using that for the frame offsets.
This change also replaces all instances of rx_buffer_info with just
rx_buffer since that is closer to the name of the actual structure being
used and can save a few extra characters.
In addition I have updated the logic for cleaning up a test frame so that
we pass an rx_buffer instead of the sk_buff. The main motivation behind
this is changes that will replace the sk_buff with just a page in the
future.

This patch makes the rings a part of the q_vector directly instead of
indirectly. Specifically on x86 systems this helps to avoid any cache
set conflicts between the q_vector, the tx_rings, and the rx_rings as the
critical stride is 4K and in order to cross that boundary you would need to
have over 15 rings on a single q_vector.
In addition this allows for smarter allocations when Flow Director is
enabled. Previously Flow Director would set the irq_affinity hints based
on the CPU and was still using a node interleaving approach which on some
systems would end up with the two values mismatched. With the new approach
we can set the affinity for the irq_vector and use the CPU for that
affinity to determine the node value for the node and the rings.

In addition we were seeing dev_watchdog hangs on igb after running the

remove the hex printk debug for the

The check for PS_WAIT_FOR_TX_ACK was inverted, the hardware should only go
to full sleep if no tx is pending.

The proper place to configure bss info is at assoc notification. So that
ath9k continues to work if the supirous bssid notification will be
removed in future.

rt2800pci is suffering from beacon skew in AP mode. Some powersaving
clients (like VOIP phones) are getting into trouble after some time
when the beacon skew is getting too big.
The ralink legacy drivers contain a function that indicates that the
beacon timer is off by 1us per tbtt. And this function works around
that by reducing the beacon interval for every 64th beacon transmission
by 64us (the smallest possible value). Do the same in rt2800pci.
This allows proper powersaving when rt2800pci is used in AP mode.

ipw2200 driver does not use these defines, it uses geo struct instead.
Therefore remove them from its header.
Note: we keep them in the ipw2100 driver's header, because the driver
still uses them.

Is possible that we stop queue and then do not wake up it again,
especially when packets are transmitted fast. That can be easily
reproduced with modified tx queue entry_num to some small value e.g. 16.
If mac80211 already hold local->queue_stop_reason_lock, then we can wait
on that lock in both rt2x00queue_pause_queue() and
rt2x00queue_unpause_queue(). After drooping ->queue_stop_reason_lock
is possible that __ieee80211_wake_queue() will be performed before
__ieee80211_stop_queue(), hence we stop queue and newer wake up it
again.
Another race condition is possible when between rt2x00queue_threshold()
check and rt2x00queue_pause_queue() we will process all pending tx
buffers on different cpu. This might happen if for example interrupt
will be triggered on cpu performing rt2x00mac_tx().
To prevent race conditions serialize pause/unpause by queue->tx_lock.

On il3945_down procedure we free tx queue data and nullify il->txq
pointer. After that we drop mutex and then cancel delayed works. There
is possibility, that after drooping mutex and before the cancel, some
delayed work will start and crash while trying to send commands to
the device. For example, here is reported crash in
il3945_bg_reg_txpower_periodic():
https://bugzilla.kernel.org/show_bug.cgi?id=42766#c10
Patch fix problem by adding il->txq check on works that send commands,
hence utilize tx queue.
