linux-next: manual merge of the net-next tree with the net tree

[Stephen Rothwell]

Hi all,

Today's linux-next merge of the net-next tree got a conflict in
net/batman-adv/routing.c between commit fe8a93b95145 ("batman-adv: make
is_my_mac() check for the current mesh only") from the net tree and
commits f86ce0ad107b ("batman-adv: Return reason for failure in
batadv_check_unicast_packet()") and 612d2b4fe0a1 ("batman-adv: network
coding - save overheard and tx packets for decoding") from the net-next
tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).
