What exact card is this and how are you generating load? If it's an fio or
iozone type command please post it here and I'll try the same thing. Are you
running cxgbei-offloaded iscsi on both the sides or is it only the initiator or
target?
I tried with 100G cards and cxgbei on both sides and didn't run into this
problem. I'm going to try with 25G cards next. 2-3GBps would be close to line
rate for those cards and it may be that the performance falls off a cliff when
you get close to line rate and start seeing pause/drops.
