Some systems send SYN packets with apparently wrong RFC1323 timestamp

Weird architectures exist that have half-assed SSB devices without SPROM attached to
their PCI busses. The architecture can register a fallback SPROM image that is
used if no SPROM is found on the SSB device.

mac80211: Notify the driver only when the beacon interval changes
Currently, the driver is unconditionally notified of beacon
interval. This is a problem in AP mode, because the driver has
to know that the beacon interval has actualy changed to recalculate
TBTT and reset the HW TSF. Fix this to make mac80211 notify the driver
only when the beacon interval has been reconfigured to a new value.

ath5k: fix hw rate index condition
Make sure we print out a warning when the index is out of bounds,
i.e. even on hw_rix == AR5K_MAX_RATES.
Also change to WARN and print text with the reported hw_rix.

ath9k: Fix hw crypto configuration for TKIP in AP mode
Incorrect Michael MIC key (RX, should have been TX) was set for the
group key in AP mode. This resulted in all broadcast frames triggering
Michael MIC errors and eventual TKIP countermeasures. The change here
sets the correct Michael MIC key based on whether the local end is the
authenticator (well, AP for now).
