Currently, the interfaces of the Mellanox Spectrum Switch QSFP ports
are all labeled eth*. Their order doesn't match the faceplate and is
different for each model.
They could be named during boot, but this isn't sufficient because they
support port splitting. After such ports are split, their port naming
begins again with eth*, and the same is true after they are unsplit again.
A hotplug script is used here that reads from the sysfs file
phys_port_name, which contains p1, p2, p3, ... for unsplit ports
and p1s0, p1s1, p1s2 for split ports.
