Not a question regarding the patch itself, but more about the comment
regarding IEEE80211_HW_WEP_INCLUDE_IV and WEP encryption. ;)

You mean the drivers that require mac80211 to do the encryption/decryption
must make sure the IEEE80211_HW_WEP_INCLUDE_IV is _not_ set?
I figured that when device requires software encryption they should set the flag
since they do not touch the frame and pass it through completely to the stack
this would also mean that the IV is passed on. Which should suggest that the
flag should be set to tell mac80211 it can use the IV.

I might be too ignorant about the specifics of the encryption steps, so I am a bit
confused about this. :S

Thanks,
