Consider below mesh topology.

        MP1
       /    \
      /      \
     MP2 --- MP3

Assume that even though MP1 & MP3 have direct mesh links, the path was
established via MP2. (MP1 <-> MP2 <-> MP3). The 1-hop mesh link MP1 <-> MP3
never be excercised till the current path is terminated. As of now, there
is no option to send data frame to pick other than primary path. So mesh
link metric between MP1 & MP3 never be updated. This series allows user
to send data to 1-hop mesh peers through unexercised mesh path.

v4: Rebased on mac80211-next top and fixed compile errors
v3: Rebased the changes on TOT
