GPIO register fields indicating the GPIO pin value and the fields
indicating the direction.
Start using a unified naming scheme for the GPIO register fields:

The TX filter bit for a station would be set by the HW
when a frame is not acked. A frame would be completed with
ATH9K_TXERR_FILT status only when the corresponding filter bit
for the destination station is already set.
Currently, un-acknowledged packets are added to the pending queue
and retried, but the "clear_dest_mask" bit in the descriptor is
set only when the TX status has been ATH9K_TXERR_FILT. This results
in packet loss and the log shows:
wlan0: dropped TX filtered frame, queue_len=0 PS=0 @4309746071
wlan0: dropped TX filtered frame, queue_len=0 PS=0 @4309746076
wlan0: dropped TX filtered frame, queue_len=0 PS=0 @4309746377
...
...
This issue can be resolved by making sure that the destination
mask is cleared when the packet is being retried and the earlier
TX status is ATH9K_TXERR_XRETRY.

It is not necessary to hold the firmware memory during the whole
driver lifetime, and obviously it does waste memory. Suppose there
are 4 ath9k-htc usb dongles working, kernel has to consume about
4*50KBytes RAM to cache firmware for all dongles. After applying the
patch, kernel only caches one single firmware image in RAM for
all ath9k-htc devices just during system suspend/resume cycle.
When system is ready for loading firmware, ath9k-htc can request
the loading from usersapce. During system resume, ath9k-htc still
can load the firmware which was cached in kernel memory before
system suspend.

QMI requests exceeding 1500 bytes are possible and
device firmware does not handle fragmented messages
very well. It is therefore necessary to increase
the maximum message size from the current 512 bytes.
The protocol message size limit is not documented
in any publicly known source, but the out of tree
driver from CodeAurora use 4 kB. This is therefore
chosen as the new arbitrary default until the real
limit is known.
This should allow any QMI message to be transmitted

Passing uids and gids on NETLINK_CB from a process in one user
namespace to a process in another user namespace can result in the
wrong uid or gid being presented to userspace. Avoid that problem by
passing kuids and kgids instead.
- define struct scm_creds for use in scm_cookie and netlink_skb_parms
that holds uid and gid information in kuid_t and kgid_t.
- Modify scm_set_cred to fill out scm_creds by heand instead of using
cred_to_ucred to fill out struct ucred. This conversion ensures
userspace does not get incorrect uid or gid values to look at.
- Modify scm_recv to convert from struct scm_creds to struct ucred
before copying credential values to userspace.
- Modify __scm_send to populate struct scm_creds on in the scm_cookie,
instead of just copying struct ucred from userspace.
- Modify netlink_sendmsg to copy scm_creds instead of struct ucred
into the NETLINK_CB.

John W. Linville says:
====================
Please pull these fixes intended for 3.6. There are more commits
here than I would like -- I got a bit behind while I was stalking
Steven Rostedt in San Diego last week... I'll slow it down after this!
There are a couple of pulls here. One is from Johannes:
"Please pull (according to the below information) to get a few fixes.
* a fix to properly disconnect in the driver when authentication or
association fails
* a fix to prevent invalid information about mesh paths being reported
to userspace
* a memory leak fix in an nl80211 error path"
The other comes via Gustavo:
"A few updates for the 3.6 kernel. There are two btusb patches to add
more supported devices through the new USB_VENDOR_AND_INTEFACE_INFO()
macro and another one that add a new device id for a Sony Vaio laptop,
one fix for a user-after-free and, finally, two patches from Vinicius
to fix a issue in SMP pairing."
Along with those...
Arend van Spriel provides a fix for a use-after-free bug in brcmfmac.
Daniel Drake avoids a hang by not trying to touch the libertas hardware
duing suspend if it is already powered-down.
Felix Fietkau provides a batch of ath9k fixes that adress some
potential problems with power settings, as well as a fix to avoid a
potential interrupt storm.
Gertjan van Wingerde provides a register-width fix for rt2x00, and
a rt2x00 fix to prevent incorrectly detecting the rfkill status.
He also provides a device ID patch.
Hante Meuleman gives us three brcmfmac fixes, one that properly
initializes a command structure, one that fixes a race condition that
could lose usb requests, and one that removes some log spam.
Marc Kleine-Budde offers an rt2x00 fix for a voltage setting on some
specific devices.
Mohammed Shafi Shajakhan sent an ath9k fix to avoid a crash related to
using timers that aren't allocated when 2 wire bluetooth coexistence
hardware is in use.
Sergei Poselenov changes rt2800usb to do some validity checking for
received packets, avoiding crashes on an ARM Soc.
Stone Piao gives us an mwifiex fix for an incorrectly set skb length
value for a command buffer.
All of these are localized to their specific drivers, and relatively
small. The power-related patches from Felix are bigger than I would
like, but I merged them in consideration of their isolation to ath9k
and the sensitive nature of power settings in wireless devices.
