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.
