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: pfcrx:Priority based Flow Control policy on RX[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
