With small packets and the "default" ring size for this NIC/driver combination, is the BQL large enough that the ring fills before one hits the BQL?
It depends on how TX completion (NAPI handler) is implemented in the driver. Say how many packets can be dequeued by each invocation. Drivers have a lot of variations there.
