Depending on the configuration of the Mellanox
Dear fellow Engineers,
I have a server with 1 x Intel 1G NIC and 3 x Mellanox 100G NICs
The NICs are named as follows
eno1, eno2(Intel NIC) ( /dev/ptp0 and /dev/ptp1 resp.)
mlnx1. mlnx2 ( Mellanox NIC1) ( /dev/ptp8 and /dev/ptp9 resp.)
mlnx3, mlnx4 ( Mellanox NIC2) ( /dev/ptp2
