Split HW init sequence into AP/STA specific parts
The AP specific init sequence includes configuration of templates, rate
classes, power mode, etc. Also unmask AP specific events in the event mbox.
Separate the differences between AP and STA init into mode
specific functions called from wl1271_hw_init. The first is called after
radio configuration and the second after memory configuration.

Note that wl1271_write32() calls cpu_to_le32() by itself, so calling

Extend channel to frequency mapping for 802.11j Japan 4.9GHz band, according to
IEEE802.11 section 17.3.8.3.2 and Annex J. Because there are now overlapping
channel numbers in the 2GHz and 5GHz band we can't map from channel to
frequency without knowing the band. This is no problem as in most contexts we
know the band. In places where we don't know the band (and WEXT compatibility)
we assume the 2GHz band for channels below 14.
This patch does not implement all channel to frequency mappings defined in
802.11, it's just an extension for 802.11j 20MHz channels. 5MHz and 10MHz
channels as well as 802.11y channels have been omitted.
The following drivers have been updated to reflect the API changes:
iwl-3945, iwl-agn, iwmc3200wifi, libertas, mwl8k, rt2x00, wl1251, wl12xx.

The aggregation code currently doesn't implement the
buffer size negotiation. It will always request a max
buffer size (which is fine, if a little pointless, as
the mac80211 code doesn't know and might just use 0
instead), but if the peer requests a smaller size it
isn't possible to honour this request.
In order to fix this, look at the buffer size in the
addBA response frame, keep track of it and pass it to
the driver in the ampdu_action callback when called
with the IEEE80211_AMPDU_TX_OPERATIONAL action. That
way the driver can limit the number of subframes in
aggregates appropriately.
Note that this doesn't fix any drivers apart from the
addition of the new argument -- they all need to be
updated separately to use this variable!

When using a mixture of AP and Station interfaces,
the hardware mode was using the type of the
last VIF registered. Instead, we should keep track
of the number of different types of vifs and set the
mode accordingly.
In addtion, use the vif type instead of hardware opmode
when dealing with beacons.
Attempt to move some of the common setup code into smaller
methods so we can re-use it when changing vif mode as
well as adding/deleting vifs.

The rx error bit parsing was changed to consider PHY errors and various
decryption errors separately. While correct according to the documentation,
this is causing spurious decryption error reports in some situations.
Fix this by restoring the original order of the checks in those places,
where the errors are meant to be mutually exclusive.
If a CRC error is reported, then MIC failure and decryption errors
are irrelevant, and a PHY error is unlikely.

Since baseband hangs are rare, but the hang check function has a high
false positive rate in some situations, we need to add more reliable
indicators.
In AP mode we can use blocked beacon transmissions as an indicator,
they should be rare enough.
In station mode, we can skip the hang check entirely, since a true
hang will trigger beacon loss detection, and mac80211 will rescan,
which leads to a hw reset that will bring the hardware back to life.
To make this more reliable, we need to skip fast channel changes
if the hardware appears to be stuck.
