RDMA/mlx5: Separate flow steering logic from main.c
Move flow steering logic to be in separate file and rename flow.c to be fs.c because it is better describe the content. Link: https://lore.kernel.org/r/20200702081809.423482-5-leon@kernel.org Signed-off-by: Leon Romanovsky <leonro@mellanox.com> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com>
