[U-Boot-Users] PATCH: add support for MII-connected ethernet switch for IPX42x

Hi,

the following patch adds support for an ethernet switch that is connected to
the MII port. In that case, there is no PHY with which auto-negotiation can
be done, and the MII port always runs in full-duplex 100MBit/s mode.
