Hi all,

It looks like that Lilijun runs the four steps are both in HOST?

Lilijun, you did not startup a VM, pass through the VF to VM, and runs l2fwd in VM?

My test steps:
1) rmmod ixgbe; modprobe ixgbe max_vfs=3,3
2) insmod dpdk-1.7.0/x86_64-native-linuxapp-gcc/kmod/igb_uio.ko
3) dpdk_nic_bind.py -b igb_uio 02:10.0 02:10.1
4) ./build/l2fwd -c 0xf -n 3 -- -p 3 -q 1

Then l2fwd run failed with error messages shown as above email.

Is my test steps correctly?
