I had already done this a week or so ago, so I skipped this part.

Hmm.. I have not noticed extra probe responses, but then again, I
haven't looked very closely on sniffer traces. Do you know whether the
driver/microcode can be modified not to reply to probes? Anyway, applied
with the if statement moved into beacon.c.

OK, applied.

I had missed this when merging in beacon configuration from Devicescape
code. Applied.

I had already done this.

Thanks! I applied the changes apart from 1 and 5 which already done.
