  Currently the E-Switch manager vport ID is supposed to be default - 0
for standalone NICs, and 0xFFFE for the SmartNICs, and is deduced from
the device PCI ID.

This uses the new method that takes the value queried from firmware as
vport ID by default. If the new method is not provided (legacy
firmware), fallback to use the PCI id approach.

Fixes: a564038699f9 ("net/mlx5: support E-Switch manager egress traffic match")
