DOC: Packet alignment
Drivers always need to pass packets that are aligned to two-byte boundaries to the stack.
Additionally, should, if possible, align the payload data in a way that guarantees that the contained IP header is aligned to a four-byte boundary. In the case of regular frames, this simply means aligning the payload to a four-byte boundary (because either the IP header is directly contained, or IV/RFC1042 headers that have a length divisible by four are in front of it). If the payload data is not properly aligned and the architecture doesn't support efficient unaligned operations, mac80211 will align the data.
With A-MSDU frames, however, the payload data address must yield two modulo four because there are 14-byte 802.3 headers within the A-MSDU frames that push the IP header further back to a multiple of four again. Thankfully, the specs were sane enough this time around to require padding each A-MSDU subframe to a length that is a multiple of four.
Padding like Atheros hardware adds which is between the 802.11 header and the payload is not supported, the driver is required to move the 802.11 header to be directly in front of the payload in that case.
