Hi,

>The keytables vary depending on the hardware:

No, it doesn't.  The hardware will automatically append the WEP ICV,
Michael hash (if told so) or AES MAC, but the WEP IV resp. AES/TKIP
sequence numbers have to be provided by the host as part of the transmit
buffer.  The IV resp. TSC is located between the 802.11 header and the
data payload.  Note that on all Atheros chips except for the 5210, there
must be a padding between the 802.11 header and the IV/TSC if the header
length is not a multiple of four.

Best regards
