The GW7901 is an IMX8M Mini based board with a KSZ9897 switch hanging off the IMX8M FEC.
In order to support a fixed-link connection to a U-Boot DSA switch some changes need to be made to the FEC driver.
Additionally, in order to support per-port unique MAC addrs for DSA we must introduce a mechanism to put the master device in promiscuous mode.
All patches are here including adding the dts for the board as well as a dsa driver and necessary patches to fec/dsa so that it is clear how this fits together.
