[PATCH v3 24/51] net/sxe2: probe all requested PF ports

[liujie5 at linkdatatechnology.com]

From: Jie Liu <liujie5 at linkdatatechnology.com>

sxe2_eth_pmd_probe() always probes a single PF port (index 0) even
when multiple ports are requested in the device arguments, so
additional PF ports are never created.

Loop over eth_da.nb_ports and probe each requested port, falling
back to a single probe when no ports are specified.

Fixes: d8e4e075ac ("net/sxe2: add probing skeleton")
