This typically shows up in the kernel log with messages like these:

ath: Could not stop RX, we could be confusing the DMA engine when we start RX up

does not result in bogus DMA traffic, however to ensure a working state
after a channel change, the hardware should still be reset.

warnings completely disappear in my tests.

It turned out that the regdomain 'APL7_FCCA' was not mapped yet.
According to Luis R. Rodriguez [Atheros' engineer] APL7 maps to
FCC_CTL and FCCA maps to FCC_CTL as well, so the attached patch
should be correct.

When the mwl8k driver attempts and fails to switch from sta to ap
firmware (or vice-versa) in the mwl8k_add_interface routine, the
mwl8k_stop routine will be called. This routine must not attempt
