Not all ports of a switch need to be used, particularly in embedded

This is missing the explanation of why reporting such ports makes sense.
Because this is a core devlink patch, we're talking really generalistic
here.
Hi Vladimir
I don't think Jakub is questioning the why. He just wants it in the
commit message.
Ack, I think we need to clearly say when those should be exposed.
Most ASICs will have disabled ports, and we don't expect NICs to
suddenly start reporting ports for all PCI PFs they may have.
Also I keep thinking that these ports and all their objects should
be hidden under some switch from user space perspective because they
are unlikely to be valuable to see for a normal user. Thoughts?
Hidden in what sense? They are already hidden in that there is no
net_device object being created for them. Are you asking for adding
another option to say, devlink show like:
devlink show -a
which would also show the ports that are disabled during a dump?
