bridge: fix compile error when compiling without IPv6 support
Some fields in "struct net_bridge" aren't available when compiling the kernel without IPv6 support. Therefore adding a check/macro to skip the complaining code sections in that case. Introduced by 2cd4143192e8c60f66cb32c3a30c76d0470a372d ("bridge: memorize and export selected IGMP/MLD querier port") Reported-by: kbuild test robot <fengguang.wu@intel.com> Signed-off-by: Linus Lüssing <linus.luessing@web.de> Signed-off-by: David S.
