Hello, I'm trying to test very simple scenario, creating two VFs and testing it with test-pmd. Unfortunately I can't make it to work DPDK Version: v17.11 (I've checked also 18.02) NIC: Niantic 82599ES 10-Gigabit SFI/SFP+ Network Connection 10fb Kernel: 4.4.0-116-generic #140-Ubuntu SMP Mon Feb 12 21:23:04 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
Steps: Creating two VFs. Binding each VF to a driver (I also tried vfio_pci with same results): ../dpdk/usertools/dpdk-devbind.py --bind=igb_uio 0000:81:10.0 ../dpdk/usertools/dpdk-devbind.py --bind=igb_uio 0000:81:10.1 ./testpmd -c 0x3 -n 4 --socket-mem 512 -- --burst=64 -i --txqflags=0xf00 --disable-hw-vlan EAL: Detected 56 lcore(s) EAL: Probing VFIO support...

Thank you all in advance. Br, Michal.
