Hi all,
Today's linux-next merge of the net-next tree got a conflict in:
drivers/net/ethernet/mellanox/mlx5/core/en_tc.c
between commit:
3e621b19b0bb ("net/mlx5e: Support TC encapsulation offloads with upper devices")
from the net tree and commits:
75c33da82736 ("net/mlx5e: TC ipv4 tunnel encap offload cosmetic changes")
9a941117fb76 ("net/mlx5e: Maximize ip tunnel key usage on the TC offloading path")
from the net-next tree.
I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging. You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.
