Hi,
The Aspeed SoCs AST2400 and AST2500 have two FTGMAC100 ethernet
controllers. This series proposes a model for this device and a way to
customize the bit definitions which are slightly different from the
Faraday definitions.
The last patch adds a fake NC-SI (Network Controller Sideband

This adds comments on the Basic mode control and status registers bit
definitions. It also adds a couple of bits for 1000BASE-T and the
RealTek 8211E PHY for the FTGMAC100 model to use.

We need to handle both registers and ITS tables. While

Flushing the ITS tables on device pre_save() is too late
