I can try some tests on same hw but testlab configuration - will give it
a try :)
That version does not work with VLANs. I have patches for it but it
needs a bit more work before sending out. Perhaps I can get back to it
next week.
Will be nice - next week i will be able to replace network controller
and install separate two 100Gbit nics into two pciex x16 slots - so can
test without hitting pcie bandwidth limits.
Does your setup have any other device types besides physical ports with
VLANs (e.g., any macvlans or bonds)?
no.
just
phy(mlnx)->vlans only config
And today again after allpy patch for page allocator - reached again
64/64 Gbit/s
with only 50-60% cpu load
today no slowpath hit for netwoking :)
But again dropped pckt at 64GbitRX and 64TX ....
And as it should not be pcie express limit -i think something more is
going on there - and hard to catch - cause perf top doestn chenged
besides there is no queued slowpath hit now
I ordered now also intel cards to compare - but 3 weeks eta
Faster - cause 3 days - i will have mellanox connectx 5 - so can
separate traffic to two different x16 pcie busses
