I applied this patch and it seems to work fine, but there
were some questions by Eric in the patchwork thread that should probably
be answered by ath9k folks.

For instance:

IEEE80211_MAX_MPDU_LEN being 3840 + somebits is suspect, since it doesnt
match 802.11 specs.

It should be more close of 2304 + MAC header (32bytes) + FCS (4 bytes) ?


Eric:  If the patch is fine as is, and if you are too busy to
submit it, I can do so with your Signed-off-by if you want.

Thanks,
Ben
