Introduce a new mbuf flag, M_PROMISC.
An mbuf packet chain with the M_PROMISC flag set contains a unicast packet
received by the link layer, which does not correspond to any configured
link layer address in the local system.
It is copied when copying m_pkthdr. It is not cleared when crossing layers.
As such, it is defined to have a flag value which is outside of the
M_PROTO* range, like M_VLANTAG has.
