This may provide L4 ports - Added new reporting in key_control - Packet is a fragment - Packet is a first fragment - Packet has encapsulation Also: - Make __skb_set_sw_hash a general function - Create functions to get a flow hash based on flowi4 or flowi6 structures without an reference to an skbuff - Ignore flow dissector return value from ___skb_get_hash. Just use whatever key fields are found to make a hash Tested: Ran 200 netperf TCP_RR instances for IPv6 and IPv4. Did not see any regression. Ran UDP_RR with 10000 byte request and response size for IPv4 and IPv6, no regression observed however I did see better performance with IPv6 flow labels due to use of flow labels for L4 hash. ==================== Signed-off-by: David S.
