Implementation of UDP GSO and GRO in WireGuard Kernel Version

Hi everyone,

I've noticed the progress made by the Tailscale team with the
userspace version of WireGuard (wireguard-go). According to their
report, the implementation of UDP GSO in the physical interface
responsible for delivering UDP packets in the tunnel and UDP GRO in
the interface receiving UDP packets was crucial for their success.

I'm curious to know if this feature has been extended to the kernel
version of WireGuard. Additionally, is there anyone currently working
on implementing these features in the kernel version, if feasible?

Kind regards.
