Consider: 'PTP (precision time protocol)'.

Consider: 'VMDq (virtual machine devise queues)'.

Consider: 'SR-IOV, max. 2 PFs, 63 VFs per PF'.

Consider to spell it as 'Tx' and 'Rx.

For consistency, 'RSS (receive side scaling)', may be?

Perhaps 'rx' -> 'Rx'.

Perhaps 'tx' -> 'Tx'.

Why is 'DEBUG' used by default? Won't it overwhelm the screen with messages?

Thank you.
