Try and ensure XDP redirect will work in KIND

This Updates the XDP program to rewrite:

  • Src Mac address
  • Dst Port

and allows us to configure if we want to run cksum
calculation on a per backend basis. It also fixes
the existing CKSUM calculation function to ignore
trailing bits.

Lastly We should be using the autogenerated bpf2go
map structs from bpf_*.go

For running in KIND make sure to turn ON GRO manually, and if using cksums (I wouldn't) turn off CKSUM offloading

Awesome, thank you Andrew. Just gonna merge this as-is for now since we're in early POC state. I'll do some testing to make sure things are working and then I'll wire up UDPRoute to it 👍
