mac80211: Use 3-address format for mesh broadcast frames.
The 11s task group recently changed the frame mesh multicast/broadcast frame
format to use 3-address. This was done to avoid interactions with widely
deployed lazy-WDS access points.
This patch changes the format of group addressed frames, both mesh-originated
and proxied, to use the data format defined in draft D2.08 and forward. The
address fields used for group addressed frames is:
In 802.11 header
ToDS:0 FromDS:1
addr1: DA (broadcast/multicast address)
addr2: TA
addr3: Mesh SA
In address extension header:
addr4: SA (only present if frame was proxied)
Note that this change breaks backward compatibility with earlier mesh stack
versions.
