Description by Hauke:
"If CONFIG_ATH_DEBUG=y is set ATH_DBG_WARN_ON_ONCE uses WARN_ON_ONCE and
returns something, but if CONFIG_ATH_DEBUG is not set it does not return
anything. Now ATH_DBG_WARN_ON_ONCE is used in the boolean expression in
an if case and is not returning anything and causes a compile error.

The AHB bus support patchset moved the table "Known PCI ids" from base.c
to pci.c - unfortunately, MODULE_DEVICE_TABLE() was not transferred.
With this fix 'modinfo ath5k' lists the alias -> pci-id lines, again.
The issue was introduced by:
commit e5b046d86f
"ath5k: Move PCI bus functions to separate file."

Suspend requires the device to be in fullsleep otherwise upon
resume the device becomes unresponsive. We need to ensure
that when we want the device to go to sleep it yields to
the request, otherwise we'll have a useless devices upon
resume. Warn when changing the power fails as we need
to look into these issues.

We should not be idle when we get the ATH9K_INT_TIM_TIMER,
otherwise its a sign of something broken in our design with

Enable the port when disabling countermeasures, and disable it on
enabling countermeasures.
This bug causes the response of the system to certain attacks to be
ineffective.
It also prevents wpa_supplicant from getting scan results, as
wpa_supplicant disables countermeasures on startup - preventing the
hardware from scanning.
wpa_supplicant works with ap_mode=2 despite this bug because the commit
handler re-enables the port.
The log tends to look like:
State: DISCONNECTED -> SCANNING
Starting AP scan for wildcard SSID
Scan requested (ret=0) - scan timeout 5 seconds
EAPOL: disable timer tick
EAPOL: Supplicant port status: Unauthorized
Scan timeout - try to get results
Failed to get scan results
Failed to get scan results - try scanning again
Setting scan request: 1 sec 0 usec
Starting AP scan for wildcard SSID
Scan requested (ret=-1) - scan timeout 5 seconds
Failed to initiate AP scan.

... and interface up.
In these situations, you are usually trying to connect to a new AP, so
keeping TKIP countermeasures active is confusing. This is already how
the driver behaves (inadvertently). However, querying SIOCGIWAUTH may
tell userspace that countermeasures are active when they aren't.
Clear the setting so that the reporting matches what the driver has
done..

This patch adds VLAN hardware support for Rhine chips.
The driver uses up to 3 additional bytes of buffer space when extracting
802.1Q headers; PKT_BUF_SZ should still be sufficient.
The initial code was provided by David Lv. I reworked it to use standard
kernel facilities. Coding style clean up mostly follows via-velocity.
Adapted to new interface for VLAN acceleration (per request of Jesse Gross).

If we break the loop when there are still skbs in tq and no skb in
rq, the skbs will be left in txq until new skbs are enqueued into rq.
In rare cases, no new skb is queued, then these skbs will stay in rq
forever.
After this patch, if tq isn't empty when we break the loop, we goto
resched directly.

This patch adds support for serial/USB-serial CAN adapters implementing the
LAWICEL ASCII protocol for CAN frame transport over serial lines.
The driver implements the SLCAN line discipline and is heavily based on the
slip.c driver. Therefore the code style remains similar to slip.c to be able
to apply changes of the SLIP driver to the SLCAN driver easily.
For more details see the slcan Kconfig entry.

With the current save power save implementation we assume a dtim period
of 1.This value is assigned based on a sanity check in the driver
eventhough we had not parsed it from mac80211.This patch obtains the actual
DTIM period from AP by parsing it from mac80211.Yet for handling
multicast traffic we may still have it as fixed rather than parsing it
from mac80211 .This does not breaks power save or anything as the sleep
duration is currently fixed in the driver.This patch may serve to improve
power save in the future by using dtim period for sleep duration and using
correct dtim period adhoc mode.

ath.ko is a common module shared between ath5k, ar9170usb, ath9k and ath9k_htc.
Adding driver specific data to the shared structure would impact all the
drivers. Handling USB device recognition for devices specific to ath9k_htc
can be handled within the driver itself.
Also, AR7010 refers to the processor used in both AR9280/AR9287 based
devices. Rename the device enumerations accordingly.
While at it, check properly for the bus type when choosing the EEPROM
base address for UB95.
