We should also patch the wpa_supplicant and hostapd ports. Also rmove peerkey
Looks like hostapd is also affected. Simple for us, not so simple if you've
purchased a commodity wirless router. I doubt most of the vendors will do
There are over a dozen (excluding tests and debugging outputs, 16 by my count)
commits our upstream have applied to hostapd and wpa_supplicant.
Rather than commit a blob, we should a) mirror their commits which can be MFCed
to stable and b) then update head and ports to the latest upstream. B could be
MFCed at a later date.
