Expand "non-promisc" packet filter to include edge cases First reported in 2013 by Sebastian Walther: https://www.winpcap.org/pipermail/winpcap-bugs/2013-May/001620.html The hardware packet filters for non-promisc mode on Windows were based on an incomplete understanding. Npcap developers reviewing MS documentation agree with Sebastian's assessment and propose the combined packet filter of NDIS_PACKET_TYPE_ALL_LOCAL | NDIS_PACKET_TYPE_DIRECTED | NDIS_PACKET_TYPE_BROADCAST | NDIS_PACKET_TYPE_MULTICAST for the inverse of "promiscuous mode" on Windows.
