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).
