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.

Hi,
If you have a switch between your phy and your cpu the speed and the duplex must be specified by the phy driver.
The best way is to add a function that request the phy status and do not wait the phy autonegociation like done in the kernel by read_status callback and it's implementation genphy_read_status.
