3. Optimisations - concatenating TX descriptors' flush, basing on
xmit_more support and combined approach for finalizing egress processing.
Thanks to HR timer buffers can be released with small latency, which is
good for low transfer and small queues. Along with the timer, coalescing
irqs are used, whose threshold could be increased back to 15.

If you are already reworking the TX path, it probably makes sense to
support BQL as well, see the Marvell skge and sky2 drivers for examples
using netdev_{tx_,}{sent,completed}_queue.

Good idea, I'll take a look.

Best regards,
Marcin
