If you apply the patch and there is a lot of wireless traffic going on
you will start getting random frames too (sniffing with tcpdump on
monitor interface or whatever). I have a couple of zd1211rw usb devices,
and both do it.

Not sure, maybe because you are sniffing all frames in the channel, not
only your BSS ones.

That patch is the mac80211 port of an older ieee80211 patch which was
not done by me. The ~0x21 is a magic value that seems to work filtering
junk frames. But i don't know what it means.

Maybe you are getting acks, or maybe it's part of the junk/random frames.

Btw, how about enabling the CR_SNIFFER_ON patch as a module parameter so
everyone is happy?
