Does anyone have any ideas on the performance regression I've reported
on the i40e at https://sourceforge.net/p/e1000/bugs/544/ ?
I've got code that with the 1.3.9 driver and kernel 4.3 can achieve 1.3
million packets per second, but if I drop in 1.3.38 or later it drops to
about 500k.
This regression affects off-the-shelf DNS server software packages too.
thanks,
