Hello, I have a question regarding the phys port id in mellanox NIC, is this feature deprecated in the latest mlnx-en-dpdk driver ?
Issue: I am working on the Ethernet controller: Mellanox Technologies MT27520 Family [ConnectX-3 Pro] NIC. I used to read the /sys/class/net/enp6s0/phys_port_id file, this will give me the value as 248a070300728f70 for port 1 and 248a070300728f71 for port 2. The modinfo details before installing the mlnx-en-dpdk is as follows # modinfo mlx4_en filename: /lib/modules/4.4.0-59-generic/kernel/drivers/net/ethernet/mellanox/mlx4/mlx4_en.ko version: 2.2-1 (Feb 2014) license: Dual BSD/GPL description: Mellanox ConnectX HCA Ethernet driver author: Liran Liss, Yevgeny Petrilin srcversion: CF3245DD50A90F3D536D0A7 depends: mlx4_core,ptp,vxlan intree: Y vermagic: 4.4.0-59-generic SMP mod_unload modversions parm: udp_rss:Enable RSS for incoming UDP traffic or disabled (0) (uint) parm: pfctx:Priority based Flow Control policy on TX[7:0].

Per priority bit mask (uint) parm: inline_thold:Threshold for using inline data (range: 17-104, default: 104) (uint) After that that I installed the mlnx-en-dpdk drivers as follows. Download and extract Mellanox divers: # cd ~/packages # wget http://www.mellanox.com/downloads/ofed/MLNX_EN-3.4-2.0.0.0/mlnx-en-3.4-2.0.0.0-ubuntu16.04-x86_64.tgz # mkdir mlnx # tar xvzf mlnx-en-3.4-2.0.0.0-ubuntu16.04-x86_64.tgz --strip-components=2 -C mlnx/ Update the /etc/apt/sources.list.d/mlnx_ofed.list file with extraction directory path as mentioned below # echo "deb file:/root/packages/mlnx/DEBS ./" > /etc/apt/sources.list.d/mlnx_ofed.list Add key to the apt tool and then update # wget -qO - http://www.mellanox.com/downloads/ofed/RPM-GPG-KEY-Mellanox | sudo apt-key add -# apt update Install the driver # apt install -y mlnx-en-dpdk I am getting the error message as follows # cat /sys/class/net/enp6s0/phys_port_id cat: /sys/class/net/enp6s0/phys_port_id: Operation not supported currently the modinfo details is as below. # modinfo mlx4_en filename: /lib/modules/4.4.0-59-generic/updates/dkms/mlx4_en.ko version: 3.4-2.0.0 (23 Nov 2016) license: Dual BSD/GPL description: Mellanox ConnectX HCA Ethernet driver author: Liran Liss, Yevgeny Petrilin srcversion: B25238324E1CDB4A38E4970 depends: mlx4_core,mlx_compat,ptp,vxlan vermagic: 4.4.0-59-generic SMP mod_unload modversions parm: udp_rss:Enable RSS for incoming UDP traffic or disabled (0) (uint) parm: pfctx:Priority based Flow Control policy on TX[7:0].
