Flow Control source port mapping for USB serdes needs to be configured
according to the GDM port nbd parameter. This is a preliminary patch
since nbd parameter is specific for the given port serdes and needs to
be read from the DTS (in the current codebase is assigned statically).

Hi Lorenzo,

Is this a fix? If so, should it have a fixes tag? And be targeted at net?
Otherwise, perhaps drop the "Fix" from the subject.

Hi Simon,

This is a preliminary patch in order to completely fix the loopback
configuration for USB serdes but the point is we are not supporting
USB serdes upstream yet (there is only OpenWrt support available at
the moment). Do you think we should target net-next or net in this
case?

If there is no bug in net - given the way net can be used with in-tree code
- then I would not tag this as a fix.

Also, I think it would be worth explaining the situation
before and after this patch.
