From 57f5877c11b244ff2315f4ba0e57b54fe013581f Mon Sep 17 00:00:00 2001 From: Florian Westphal <fw@strlen.de> Date: Tue, 30 Sep 2014 10:59:18 +0200 Subject: [PATCH] netfilter: bridge: build br_nf_core only if required Eric reports build failure with CONFIG_BRIDGE_NETFILTER=n We insist to build br_nf_core.o unconditionally, but we must only do so if br_netfilter was enabled, else it fails to build due to functions being defined to empty stubs (and some structure members being defined out). Also, BRIDGE_NETFILTER=y|m makes no sense when BRIDGE=n.
