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 -- Ben Greear Candela Technologies Inc http://www.candelatech.com
