wlcore/wl12xx/wl18xx: introduce quirk to remove TKIP header space

18xx chips do not require extra space in the TKIP header. Introduce a
new HW quirk to allow us to make this feature arch-specific. 12xx chip
will now have this quirk.

wlcore/wl12xx/wl18xx: handle spare blocks spacials cases per arch

Add a HW op for getting spare blocks.

12xx cards require 2 spare blocks for GEM encrypted SKBs, regardless
of VIFs or keys programmed into the FW.

18xx cards require 2 spare blocks when there are any connected TKIP or
GEM VIFs. For now always return 2 spare blocks, as this works with all
networks. The special case TKIP/GEM functionality is added at a later
patch.

wlcore: add stop reason bitmap for waking/starting queues

Allow the driver to wake/stop the queues for multiple reasons. A queue
is started when no stop-reasons exist.

Convert all wake/stop queue calls to use the new API.

Before, a stopped queue was almost synonymous a high-watermark on Tx.
Remove a bit of code in wl12xx_tx_reset() that relied on it.

Internal packets arriving from mac80211 are also discarded when a queue
is stopped. A notable exception to this is the watermark reason, which
is a "soft"-stop reason. We allow traffic to gradually come to a halt,
but we don't mind spurious packets here and there. This is merely a flow
regulation mechanism.

Based on a similar patch by Eliad Peller <eliadWizery.com>.

wlcore: stop queues on Tx flush

Stop network queues during Tx flush, c$and also drop other internal
mac80211 packets (mgmt) that may arrive when the queues are stopped.

When flush is done all driver queues are clear, forcefully if needed.

Protect the Tx flush operation with a new mutex, to prevent concurrency
that can mess us queue state.

wlcore/wl12xx/wl18xx: implement op_set_key per HW arch

The 12xx set_key just calls the common wlcore_set_key function, in order
to program the keys into the FW.

The 18xx variant changes the spare block count when a GEM or TKIP
key is set. Also modify the get_spare_blocks HW op for 18xx to return
the correct numbers of spare blocks, according to what is currently
set in FW.

wlcore: do not send stop fwlog cmd if fw is hanged (INTERNAL)

If the driver received a watchdog interrupt then the
assumption is that the fw is hanged. Avoid sending
the stop fwlog command in case of a watchdog recovey
to avoid waiting for the 2 seconds timeout of the command.

mac80211: don't stop beaconing when going offchannel (INTERNAL)

wl12xx manages the channel per-role, so there is no need
to explicitly stop beaconing when doing offchannel operations,
as the device will take care of it by itself.

This way we avoid redundant stop_ap/start_ap calls when
doing offchannel operations on another vif (e.g. auth)

NOTE: this patch shouldn't go upstream. we have to come up
with more generic multi-channel solution...

wlcore: wait for ROLE_STOP_COMPLETED event (INTERNAL)

We previously didn't wait for this event, as it wasn't
necessary, and sometimes the fw didn't send it.

However, this event is now needed again for some roaming
scenarios. if we'll encounter cases in which we don't get
the event - they will be treated as fw bugs.
wlcore/wl18xx/wl12xx: add version and timestamp strings (INTERNAL)

In order to allow better version control, add version
and timestamp strings into the wl12xx module.

These strings will be printed on driver load, and when
reading the driver_state.

(this is not going to work well in compat, because it
copies all the files instead of compiling them in the
original tree, so the version of the compat tree will
appear as the driver version. we can workaround it
with the additional makefile hacks...)

NOTE: I couldn't find how to make one module recompile
when the .h file of another module was changed, so i
just duplicated it for now.

wlcore: force recheck of version.h and use -dirty if needed (INTERNAL)

If the tree was changed and unstaged or if a new tag was added, we
were not regenerating the version.h file, so it would contain outdated
information.

To fix this, force the version.h file to be rechecked during make and
use __TIMESTAMP__ instead of using the shell's date command, so that
we don't regenerate it everytime.

Additionally, use --dirty in git describe to mark dirty trees as such.

Thanks Eliad for the help with this.

It's good to print out the driver version as early as possible, so we
can also catch problems with the probe.  Move the version info to init.

Also, change "compilation time" to "timestamp", because it doesn't
mean the compile time anymore but the modification time of the source
file that generates it.
