[PATCH wireless-next 0/2] wifi: b43: MAC filter and 64-bit DMA fixes for the BCM4360

[Andreas Wendleder]

Two fixes found while bringing up a BCM4360 (MacBookAir6,1). Neither
depends on the AC PHY.

 1. After an interface restart nothing was received until some other
    change touched the filter: b43_op_start() zeroes wl->filter_flags,
    but mac80211 computes the change against its own cached flags.
 2. The 64-bit DMA engines of the BCM4352/BCM4360 cores use bus addresses
    in the index and status registers. They are detected by probe, as
    brcmsmac does; engines that keep offsets are untouched.

The rest of the BCM4360 support will follow once these land.

Tested on a MacBookAir6,1 (BCM4360, core revision 42) with the whole
BCM4360 support applied.

  wifi: b43: reprogram the MAC filter after an interface restart
  wifi: b43: handle 64-bit DMA engines whose index registers hold bus
    addresses
