Remarks:
This function gets a
hardware filter on the incoming packets. The constants that define
the filters are declared in the file ntddndis.h. The input
parameters are the adapter on which the filter must be defined, and
the pointer to the variable to save current filter. Here is a list
of the most useful filters:
- NDIS_PACKET_TYPE_PROMISCUOUS: sets
the promiscuous mode. Every incoming packet is accepted by the
adapter.
- NDIS_PACKET_TYPE_DIRECTED: only
packets directed to the workstation's adapter are accepted.
- NDIS_PACKET_TYPE_BROADCAST: only
the broadcast packets are accepted.
- NDIS_PACKET_TYPE_MULTICAST: only
the multicast packets belonging to the groups of which this adapter
is a member are accepted.
- NDIS_PACKET_TYPE_ALL_MULTICAST:
every multicast packet is accepted.
- NDIS_PACKET_TYPE_ALL_LOCAL: all
local packets, i.e. NDIS_PACKET_TYPE_DIRECTED +
NDIS_PACKET_TYPE_BROADCAST + NDIS_PACKET_TYPE_MULTICAST
