[ Upstream commit e2ab5aa11f191b54514f063a5b5c29f3559f4ab7 ]
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.
