Hi, when running relfex i got the error below

EAL: Error - exiting with code: 1
Cause: No Ethernet ports - exiting

however, the Ethernet controller(82545EM Gigabit Ethernet Controller (Copper) 100f) has been bound to igb_uio and it's also ok when running examples in dpdk such as l2fwd

Thanks for reply, but in cfg file i have configured as

devices="0000:02:01.0"
nvme_devices="0000:03:00.0"

and after binding nic when using dpdk-devbind.py--status it shows as

Network devices using DPDK-compatible driver
0000:02:01.0 '82545EM Gigabit Ethernet Controller (Copper) 100f' drv=igb_uio
unused=uio_pci_generic
Network devices using kernel driver
0000:02:06.0 '82545EM Gigabit Ethernet Controller (Copper) 100f' if=ens38 drv=e1000
unused=igb_uio,uio_pci_generic Active

Your setup looks correct. However, I see you are using a different NIC than the ones we have tested ReFlex with, so the driver for this NIC is not included by default in the ReFlex dp/Makefile. You will need to add the necessary .a files to the DPDK_LIBS line in dp/Makefile and make sure to compile DPDK to include the driver for your NIC so those .a files are in the DPDK repo you are using for ReFlex. As an example, you can look at how this commit adds support for the Mellanox Connect X-5 NIC in the mlx5 branch of reflex: 7a2e7ac
