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

Hi all,

Today's linux-next merge of the net-next tree got conflicts in
net/batman-adv/translation-table.c between commits 03fc3070457d
("batman-adv: in case of roaming mark the client with TT_CLIENT_ROAM")
and 797399b415b7 ("batman-adv: delete global entry in case of roaming")
from the net tree and commit 48100bac89a6 ("batman-adv: create a common
substructure for tt_global/local_entry") from the net-next tree.

I fixed it up (I think - see below) and can carry the fix as necessary.

Cheers,
