From 867b1db874c93ceb86f9e10ef021e70c38cc4b4d Mon Sep 17 00:00:00 2001 From: Horatiu Vultur Date: Sat, 12 Feb 2022 21:03:43 +0100 Subject: [PATCH] net: lan966x: Fix when CONFIG_IPV6 is not set When CONFIG_IPV6 is not set, then the linking of the lan966x driver fails with the following error: drivers/net/ethernet/microchip/lan966x/lan966x_main.c:444: undefined reference to `ipv6_mc_check_mld' The fix consists in adding a check also for IS_ENABLED(CONFIG_IPV6) Fixes: 47aeea0d57e80c ("net: lan966x: Implement the callback SWITCHDEV_ATTR_ID_BRIDGE_MC_DISABLED") Reported-by: kernel test robot Signed-off-by: Horatiu Vultur Signed-off-by: David S.
