mac80211: clarify alignment docs, fix up alignment
Not all drivers are capable of passing properly aligned frames, in particular with mesh networking no hardware will support completely aligning it correctly. This patch adds code to align the data payload to a 4-byte boundary in memory for those platforms that require this, or when CONFIG_MAC80211_DEBUG_PACKET_ALIGNMENT is set.
