This patch adds a helper function called bpf_get_xdp_hash to calculate
the hash for a packet at the XDP layer. In the helper function, we call
the kernel flow dissector in non-skb mode by passing the net pointer
to calculate the hash.

This patch adds a helper function called bpf_get_xdp_hash to calculate
the hash for a packet at the XDP layer. In the helper function, we call
the kernel flow dissector in non-skb mode by passing the net pointer
to calculate the hash.

- accounted for vlans(David Ahern)
