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.
