From e689e998e102100bdf7991763d4c244704846f2d Mon Sep 17 00:00:00 2001 From: Saeed Mahameed Date: Fri, 1 Nov 2019 15:38:30 -0700 Subject: net/mlx5e: TC, Stub out ipv6 tun create header function Improve mlx5e_route_lookup_ipv6 function structure by avoiding #ifdef then return -EOPNOTSUPP in the middle of the function code. To do so, we stub out mlx5e_tc_tun_create_header_ipv6 which is the only caller of this helper function to avoid calling it altogether when ipv6 is compiled out, which should also cleanup some compiler warnings of unused variables.
