Subject: [PATCH] net: airoha: Make flow control source port mapping dependent
on nbq parameter
Flow control source port mapping for USB serdes needs to be configured
according to the GDM port nbq parameter. This is a preliminary patch
since nbq parameter is specific for the given port serdes and needs to
be read from the DTS (in the current codebase is assigned statically).
