Hi all,
Today's linux-next merge of the rdma tree got a conflict in:
drivers/net/ethernet/mellanox/mlx5/core/fs_core.c
between commit:
60ab4584f5bf ("net/mlx5_core: Set flow steering dest only for forward rules")
from the net-next tree and commit:
b3638e1a7664 ("net/mlx5_core: Introduce forward to next priority action")
from the rdma tree.
I fixed it up (see below) and can carry the fix as necessary (no action
is required).

Cheers,
Stephen Rothwell
