====================
sfc: more encap offloads
This patch series adds support for RX checksum offload of encapsulated packets.
It also adds support for configuring the hardware's lists of UDP ports used for
VXLAN and GENEVE encapsulation offloads. Since changing these lists causes the
MC to reboot, the driver has been hardened against reboots, which used to be
considered an exceptional occurrence but are now normal.
