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
