-Subject: [PATCH 08/11] netfilter: don't allocate space for arp/bridge hooks
- unless needed
-
-no need to define hook points if the family isn't supported.
-Because we need these hooks for either nftables, arp/ebtables
-or the 'call-iptables' hack we have in the bridge layer add two
-new dependencies, NETFILTER_FAMILY_{ARP,BRIDGE}, and have the
-users select them.
