Unable to compile i40e driver on Centos7

[Rajisha]

Hi

We are having the i40e driver version as 2.8 with NIC XL710.

modinfo i40e | grep ver
filename: /lib/modules/3.10.0-1160.42.2.rt56.1182.el7.x86_64/kernel/drivers/net/ethernet/intel/i40e/i40e.ko.xz
version: 2.8.20-k
description: Intel(R) Ethernet Connection XL710 Network Driver
rhelversion: 7.9
srcversion: F7480CBA290FAAF2FAF95C7
vermagic: 3.10.0-1160.42.2.rt56.1182.el7.x86_64 SMP preempt mod_unload modversions

We are trying to run Flexran sample-app for DU and RU (https://docs.o-ran-sc.org/projects/o-ran-sc-o-du-phy/en/latest/Setup-Configuration_fh.html) , but we see below error:

EAL: Detected 128 lcore(s)
EAL: Detected 4 NUMA nodes
EAL: Auto-detected process type: PRIMARY
EAL: Multi-process socket /var/run/dpdk/wls_0/mp_socket
EAL: Selected IOVA mode 'PA'
EAL: Probing VFIO support...
EAL: PCI device 0000:17:02.1 on NUMA socket 0
EAL: probe driver: 8086:154c net_i40e_vf
EAL: Driver cannot attach the device (0000:17:02.1)
EAL: Failed to attach device on primary process
sample-app: Network port doesn't exist

We are using dpdk version  19.11, so we have to upgrade the driver to 2.9 which is compatible with the dpdk version.

We tried downloading the i40e driver 2.9 version (Intel® Network Adapter Driver for PCIe* 40 Gigabit Ethernet Network Connections under Linux*), but we see errors while compiling.

When we try to solve this error, other dependency errors are coming.

Can anyone help us in upgrading the i40e driver version from 2.8 to 2.9.

Thank you.
