OK, so you're measuring the inter-packet gap and in that burst of 11
(or whatever many) packets it's 96 bit times between every packet, yes?
Interesting. Can you also try 'pre-loading' the TX ring with a bunch of
packets and then writing the values 0, 1, 2, 3 ... n-1 to the TXD register
with back-to-back MMIO writes (instead of doing a single write of the
value 'n'), and check what inter-packet gap you get then?
cheers,
Lennert
