netfilter: bridge: fix Kconfig unmet dependencies
Before f5efc69 ("netfilter: nf_tables: Add meta expression key for bridge interface name"), the entire net/bridge/netfilter/ directory depended on BRIDGE_NF_EBTABLES, ie. on ebtables. However, that directory already contained the nf_tables bridge extension that we should allow to compile separately. In f5efc69, we tried to generalize this by using CONFIG_BRIDGE_NETFILTER which was not a good idea since this option already existed and it is dedicated to enable the Netfilter bridge IP/ARP filtering. Let's try to fix this mess by: 1) making net/bridge/netfilter/ dependent on the toplevel CONFIG_NETFILTER option, just like we do with the net/netfilter and net/ipv{4,6}/netfilter/ directories. 2) Changing 'selects' to 'depends on' NETFILTER_XTABLES for BRIDGE_NF_EBTABLES. I believe this problem was already before f5efc69: warning: (BRIDGE_NF_EBTABLES) selects NETFILTER_XTABLES which has unmet direct dependencies (NET && INET && NETFILTER) 3) Fix ebtables/nf_tables bridge dependencies by making NF_TABLES_BRIDGE and BRIDGE_NF_EBTABLES dependent on BRIDGE and NETFILTER: warning: (NF_TABLES_BRIDGE && BRIDGE_NF_EBTABLES) selects BRIDGE_NETFILTER which has unmet direct dependencies (NET && BRIDGE && NETFILTER && INET && NETFILTER_ADVANCED) net/built-in.o: In function `br_parse_ip_options': br_netfilter.c:(.text+0x4a5ba): undefined reference to `ip_options_compile' br_netfilter.c:(.text+0x4a5ed): undefined reference to `ip_options_rcv_srr' net/built-in.o: In function `br_nf_pre_routing_finish': br_netfilter.c:(.text+0x4a8a4): undefined reference to `ip_route_input_noref' br_netfilter.c:(.text+0x4a987): undefined reference to `ip_route_output_flow' make: *** [vmlinux] Error 1 Reported-by: Jim Davis <jim.epost@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> Signed-off-by: David S.

ebtables is a general, extensible frame/packet identification
framework. Say 'Y' or 'M' here if you want to do Ethernet
