Are you seeing any error messages in the kernel logs?

The Tx queue lenght constants are 32 (total size) and 12 (effective
size).  Something in the system is delaying for 16 packets, which is
characteristic of other Linux drivers.

Check the /proc/interrupts count to verify that you are getting the
interrupt count you expect -- one per packet.
