I have an 1g sx optical tap.
tap port A : sender server (running tcpreplay)
tap port B : receiver server
tap port M : monitor server (running dpdk l2fwd)
Reproduce step
1. In monitor server, bind igb_uio to intel 82599es nic. (then link led is
off)
2. In sender server, start tcpreplay
3. In monitor server, run l2fwd...but link is never came up
As soon as sender stops tcpreplay, or doesn't start tcpreplay, then link is
up.
What am I doing wrong?
If I run tcpdump instead of l2fwd, trafffic is captured correctly. so I'm
sure cabling is fine.
