if_vtnet: Add support for CTRL_GUEST_OFFLOADS feature

Authored by bryanv on Jan 2 2021, 9:07 PM.



This allows the Rx checksum and LRO to be modified without a full
reinit of the device.

Remove IFCAP_RXCSUM_IPV6 from the interface capabilities since in
VirtIO Rx checksums are just enabled or disabled for all protocols.

Properly update IFCAP_LRO if LRO is becomes disabled when Rx
checksums are disabled.
