This patch is apparently the cause of BPF self-tests failures:

test_empty_skb:FAIL:ret: veth ETH_HLEN+1 packet ingress
[redirect_ingress] unexpected ret: veth ETH_HLEN+1 packet ingress
[redirect_ingress]: actual -34 != expected 0
test_empty_skb:PASS:err: veth ETH_HLEN+1 packet ingress
[redirect_egress] 0 nsec
test_empty_skb:FAIL:ret: veth ETH_HLEN+1 packet ingress
[redirect_egress] unexpected ret: veth ETH_HLEN+1 packet ingress
[redirect_egress]: actual -34 != expected 1

Before submitting an eventual next revision, please very that BPF
self-tests are happy.

Thanks,

Paolo
