That's not really right - the padding shouldn't have been added to the first subframe in the first place as the last one shouldn't have padding at all. There's also a separate bug in that the A-MSDU subframe length should NOT include the padding. My colleague Sara (CC'ed now) has a patch to fix all of this (we just did that this morning). I'll send it out tomorrow morning. Can I bother you to try that? We'd have to fix the first point independently though, or I guess we can roll that into our bugfix too, which would you prefer? johannes
