Subject: [PATCH] net: mscc: ocelot: make phy_mode a member of the common
|
||
|
|
struct ocelot_port
|
||
|
|
|
||
|
|
The Ocelot switchdev driver and the Felix DSA one need it for different
|
||
|
|
reasons. Felix (or at least the VSC9959 instantiation in NXP LS1028A) is
|
||
|
|
integrated with the traditional NXP Layerscape PCS design which does not
|
||
|
|
support runtime configuration of SerDes protocol. So it needs to
|
||
|
|
pre-validate the phy-mode from the device tree and prevent PHYLINK from
|
||
|
|
attempting to change it. For this, it needs to cache it in a private
|
||
|
|
variable.
|
||
