I agree. We have the following chunk of code in the decrypt handler:
/*
* No point in finding a key and decrypting if the frame is neither
* addressed to us nor a multicast frame.
*/
if (!(rx->flags & IEEE80211_TXRXD_RXRA_MATCH))
return TXRX_CONTINUE;
the RA_MATCH flag is cleared when the frame is neither multicast nor
addressed to us so I don't see how we can get into WEP decryption. A
concurrently running tcpdump might help though without the keys it'd be
hard to verify everything.
The fact that ipw3945 doesn't print out any such messages is hardly
indicative of a mac80211 problem btw, maybe it simply doesn't contain
such debug messages.
