Merge branch 'enic-vxlan-offload'
Govindarajulu Varadarajan says: ==================== enic: add vxlan offload support This series adds vxlan offload support for enic driver. The first patch adds vxlan devcmd for configuring vxland offload parameters. Second patch adds ndo_udp_tunnel_add/del and offload on rx path. There are to modes in which fw supports vxlan offload. mode 0: fcoe bit is set for encapsulated packet. fcoe_fc_crc_ok is set if checksum of csum is ok. This bit is or of ip_csum_ok and tcp_udp_csum_ok mode 2: BIT(0) in rss_hash is set if it is encapsulated packet. BIT(1) is set if outer_ip_csum_ok/ BIT(2) is set if outer_tcp_csum_ok Some hw supports only mode 0, some support mode 0 and 2. Driver gets the supported modes bitmap using get_supported_feature_ver devcmd and selects the highest mode both driver and fw supports. Third patch adds offload support on tx path by adding enic_features_check(). v2: Order local variable declarations from longest to shortest line, on all three patches. ==================== Signed-off-by: David S.
