In Linux 4.5, when CONFIG_NET_CLS_ACT is defined, compilation of out of tree modules breaks with undeclared functions/constants.

Unfortunately I'm not sure what the correct fix is, maybe the uapi folks could help, but i attached a simple testcase and build log (Makefile is straight from kernelnewbies).
Hmm, your fail.c test case only contains '#include <net/ipv6.h>'? Note, upstream kernel never cared about out-of-tree modules, only in-tree code. ;) Did you run into an issue with any in-tree code? Thanks, Daniel
