Members

PortID

Port ID of the frame.

PeerID

Peer ID of the frame (only if TargetPriorityQueueing is false).

ExTID

Extended TID of the frame (only if TargetPriorityQueueing is false).

IsUnicast

Specifies if the frame is for a unicast recipient address.

bAllowLegacyRates

Specifies if legacy rates should be used for transmitting the frame.

Ethertype

Specifies the Ethertype of the frame.

bTxCompleteRequired

Specifies if an NdisWdiTxSendCompleteIndication is required for this frame.

PnLength

Specifies the PnLength for the frame. This is only applicable to Requeued/Replayed TX frames. Otherwise, set to zero.

TxCost

Specifies the number of credits required to dequeue the frame.

ExemptionAction

Specifies the WDI_EXEMPTION_ACTION_TYPE value for this frame.

MpduPn

Specifies the MpduPn for the frame. This is only applicable to Requeued/Replayed TX frames. Otherwise, set to zero.

ReplayIHVReserved0

Reserved for use by the IHV miniport for Requeued/Replayed TX frames. This is only applicable to Requeued/Replayed TX frames. Otherwise, set to zero.

ReplayIHVReserved1

Reserved for use by the IHV miniport for Requeued/Replayed TX frames. This is only applicable to Requeued/Replayed TX frames. Otherwise, set to zero.

SeqCtl

Specifies the SeqCtl (if necessary). This is only applicable to Requeued/Replayed TX frames. Otherwise, set to zero.

wPad

Reserved.
