Hi there,
I'm running DPDK with a dual-port 82546EB NIC, but the performance is
really low (about 150Mbit/s).
Somebody told me that I should disable flow control and try again, but I
don't know how to do it.
So, I have 2 questions:
- How to disable flow control?
- If the performance doesn't get better after disabling flow control, what
should I do next?
Any advice and suggestions will be greatly appreciated.
Thanks in advance!

I have checked again, FC is disabled by default (I'm running the l2fwd
example).
So what's the problem with my NIC speed?
