NET_PACKET_FILTER_FLAGS enumeration (netadapter.h)

The NET_PACKET_FILTER_FLAGS enumeration describes a network adapter's receive packet filters.

Syntax

typedef enum _NET_PACKET_FILTER_FLAGS {
  NetPacketFilterFlagDirected = 0x00000001,
  NetPacketFilterFlagMulticast = 0x00000002,
  NetPacketFilterFlagAllMulticast = 0x00000004,
  NetPacketFilterFlagBroadcast = 0x00000008,
  NetPacketFilterFlagPromiscuous = 0x00000020
} NET_PACKET_FILTER_FLAGS;

Constants

NetPacketFilterFlagDirected Value: 0x00000001 The network adapter can filter directed packets. Directed packets contain a destination address equal to the MAC address of the NIC.
NetPacketFilterFlagMulticast Value: 0x00000002 The network adapter can filter multicast packets whose destination MAC address matches an address in the multicast address list.
NetPacketFilterFlagAllMulticast Value: 0x00000004 The network adapter can filter all multicast address packets, not just the ones enumerated in the multicast address list.
NetPacketFilterFlagBroadcast Value: 0x00000008 The network adapter can filter broadcast packets.
NetPacketFilterFlagPromiscuous Value: 0x00000020 The network adapter can filter all packets regardless of whether VLAN filtering is enabled or not and whether the VLAN identifier matches or not.

Remarks

The driver uses the NET_PACKET_FILTER_FLAGS enumeration to specify the net adapter's receive packet filters in the NET_ADAPTER_RECEIVE_FILTER_CAPABILITIES structure.

An initialized NET_ADAPTER_RECEIVE_FILTER_CAPABILITIES structure is an input to NetAdapterSetReceiveFilterCapabilities.

Important

If the driver doesn't report support for all of the packet filters expected by an upper layer, NetAdapterCx will fail the OID_GEN_CURRENT_PACKET_FILTER request, which causes the upper layer to fail to bind to your driver. For reliable binding, your driver must report support for all packet filter types.
