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.
