Mulitiple Packet Send in NIC

hi,
I am developing a driver for 21143 based NIC. In the
miniportqueryinformation I am returning 8 for the
OID_GEN_MAXIMUM_SEND_PACKETS query. I have registered
a miniportmultiplesend function but the upper layer
sends me only 1 packet at a time. Due to this the
performance is affected.
Please let me know what else do i need to do.
