Tom Herbert 35f59d862f vxlan: Add support for remote checksum offload 
This patch adds support to remote checksum checksum offload
to VXLAN. This patch adds remcsumtx and remcsumrx to ip vxlan
configuration to enable remote checksum offload for transmit
and receive on the VXLAN tunnel.

https://tools.ietf.org/html/draft-herbert-vxlan-rco-00

Example:

ip link add name vxlan0 type vxlan id 42 group 239.1.1.1 dev eth0 \
    udpcsum remcsumtx remcsumrx

Testing:

Ran single netperf over mlnx4 to illustrate the effest:

- Without RCO (UDP csum set to zero)
  4335.99 Mbps
- With RCO enabled
  7661.81 Mbps
