My bet is that your miniport is not managing OID_GEN_CURRENT_PACKET_FILTER

and you use it in promiscuous mode, the WinPcap protocol driver sets the
PACKET_FILTER to NDIS_PACKET_TYPE_PROMISCUOUS. Otherwise it uses
Do all the ICMP echo requests get "discarded" by the TCP/IP stack when
ethereal is off, or just some of them?
Have a nice day
