net/mlx5e: Extract remaining tunnel encap code to dedicated file
Move set_encap_dests() and clean_encap_dests() to the tunnel encap dedicated file. And rename them to mlx5e_tc_tun_encap_dests_set() and mlx5e_tc_tun_encap_dests_unset(). No functional change in this patch. It is needed in the next patch. Signed-off-by: Chris Mi <[email protected]> Signed-off-by: Saeed Mahameed <[email protected]>
