cards are shutting down if I execute dpdk-devbind.py

The moment I enabled DPDK, Network card is going down.

$ lspci | grep -i intel
c3:00.0 Ethernet controller: Intel Corporation Ethernet Controller E810-C for QSFP (rev 02)
c3:00.1 Ethernet controller: Intel Corporation Ethernet Controller E810-C for QSFP (rev 02)

$ sudo dpdk-devbind.py -b vfio-pci c3:00.0 c3:00.1

After this, cards are going down. EAL is giving error
EAL: Requested device 0000:c3:00.1 cannot be used
EAL: Error - exiting with code: 1
Cause: Error: number of ports must be even

 

I am seeing cards are shutting down because the green LED is no more glowing after running devbind
