Thanks for your review.

The measurement is simple: record how much time we spent in mvneta_rx_swbm()
for receiving 1GB data, something as below:

Please use a standard tool for measuring performance, rather than profiling
the driver and trying to derive numbers that way.

If possible in your setup, I suggest pushing 64B (and other sizes)
packets uni or bidirectionally via 2 ports in L2 bridge mode. It's a
good stress test, you'd get some meaningful numbers (also check cpu
consumption with mpstat in the meantime).

Best regards,
Marcin
