The firmware type and the project number fields in the firmware
version number, cannot be checked as if they increase sequentially,
because the former is the firmware type and the latter is an internal
project number. There's no guarantee that these numbers will remain
incremental, so use WLCORE_FW_VER_IGNORE.

The firmwares version string contain 5 integers. We used to consider
all the digits (except for the first one, which indicates the chip) as
linearly increasing version numbers. This is not correct, because
some of the integers indicate type of firmware (eg. single-role
vs. multi-role) or the internal project it was created for.
Besides, this varies a bit from chip to chip, so we need to make the
firmware version checks more flexible (eg. allow the lower driver to
ignore some of the integers). Additionally, we need to change the
code so that we only check for a linearly increasing number on the
fields where this actually makes sense.

We don't distinguish between STA and AP firmwares anymore, so the
firmware version checking and quirks setting in wl12xx isn't needed
anymore.
Remove implementation of .identify_fw in wl12xx and deprecated
definitions. Don't remove the op entirely from wlcore, because it may
be needed for more fine-grained checking later.

On the RF3290,RF5360,RF5370,RF5372,RF5390,RF5392
radio frontends, the VCO calibration can be
controlled via the RFCSR3 register. The current
code uses the RFCSR30_RF_CALIBRATION constant to
enable the calibration, however that belongs to
the RFCSR30 register. Although the values of the
constant is correct, but using that for another
register is confusing.
Add a new definition for the VCO calibration enable
bit of the RFCSR3 register and use that in the
relevant places in order to avoid confusions.

On A-MPDU frames, the hardware only reports valid

This patch fixes it by flagging everything but the
last subframe in an A-MPDU to tell mac80211 to

the empty value (= 0 dbm) will distort the

There are 2 different things:
- sub-menu for "Atheros Wireless cards" family
- module ath.ko with common Atheros code
Until now, they both used to depend on the same Kconfig variable ATH_COMMON.
Thus, being "Atheros card" and "depending on ath.ko" was the same.
To allow module to belong to the
"Atheros Wireless cards" family but not use ath.ko,
2 conditions above need to be separated.
So, this patch introduce new Kconfig variable ATH_CARDS for belonging
to the "Atheros Wireless Cards" family; while ATH_COMMON becomes hidden
variable to express dependency on common Atheros code in ath.ko. Modules
that depend on this common code now express it by setting ATH_COMMON.
Right now, ath6kl do not depend on common code and thus do not set ATH_COMMON.
