openvswitch: Reject ct_state masks for unknown bits
Currently, 0-bits are generated in ct_state where the bit position is undefined, and matches are accepted on these bit-positions. If userspace requests to match the 0-value for this bit then it may expect only a subset of traffic to match this value, whereas currently all packets will have this bit set to 0. Fix this by rejecting such masks. Signed-off-by: Joe Stringer <joestringer@nicira.com> Acked-by: Pravin B Shelar <pshelar@nicira.com> Acked-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: David S.
