Hi, I am completely newbie to bpf, I am trying to change skb destination MAC for cilium https://github.com/cilium/cilium/issues/16503#issue-918040655, the bpf build went fine but appears having problem to pass the verifier at bpf load time, it is beyond my skill level to trouble shoot bpf load issue, so I am wondering if a bpf helper to help set skb src/dst MAC would make life easier for newbie like me :) Regards, Vincent
