> This patch adds a capability negotiation between VF and PF using ENCAP/
> ENCAP_CSUM offload flags in order for the VF to support outer checksum
> and TSO offloads for encapsulated packets. These capabilities were assumed
> by default and enabled in current hardware. Going forward, these features
> needs to be negotiated with PF before advertising to the stack.
> Additionally, strip out the mac.type checks for X722 since outer checksums
> are enabled based on the ENCAP_CSUM offload negotiation flag and
> maintain consistency between drivers in how the features are configured.
