netfilter: bridge: fix CONFIG_NF_DEFRAG_IPV4/6 related warnings/errors
br_nf_ip_fragment() is not needed when neither CONFIG_NF_DEFRAG_IPV4 nor CONFIG_NF_DEFRAG_IPV6 is set. struct brnf_frag_data must be available if either CONFIG_NF_DEFRAG_IPV4 or CONFIG_NF_DEFRAG_IPV6 is set. Fixes: efb6de9b4ba0 ("netfilter: bridge: forward IPv6 fragmented packets") Reported-by: kbuild test robot <fengguang.wu@intel.com> Signed-off-by: Bernhard Thaler <bernhard.thaler@wvnet.at> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
