intel 100 Gbps Network card shutting down after enabling dpdk

[Lokesh Chakka]

hello,

Recently I have bought one intel network card

https://ark.intel.com/content/www/us/en/ark/products/210969/intel-ethernet-network-adapter-e8102cqda2.html

The moment I do devbind, cards are shutting 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 following 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

Did anyone face this issue or anyone know how to fix the issue?

Thanks & Regards
