At EuroBSDCon last year Mike Larkin gave me an AR5211 ath(4) device
which fails at WEP/WPA. For every encrypted frame it sends, a decryption
failure shows up in netstat -W on the AP.
This diff ports a chunk from the AR5212 code which disables hardware
WEP key table entries. This fixes the issue for me. Note that ath(4)
uses software encryption/decryption for WEP/WPA.
ok?
Thanks for the card, Mike!
