Yes, nh is almost always set to right value, unlike h.
"Almost" is because, it is possible to see it shifted
when packet is sent via raw packet socket with an complicaed MAC header.
Shortly, corresponding pointer is reliable when packet originated
by corresponding part of code. h is reliable, when packet is sourced
by tcp/udp, nh - when it is srourced by a protocol.
The only 100% right way is to parse from skb->data and skip mac header
at el.
