Subject: [net 01/17] net/mlx5e: Extract remaining tunnel encap code to dedicated file
From: Chris Mi <cmi@...dia.com>
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.
