Hello Kevin,

The previous version of this driver implemented a shell command to manually comfigure the switch. It did not integrate with the PHY infrastructure to allow a MAC to use it as its PHY. This is a complete rewrite to allow this switch to function as a driver. Since none of the original driver remains, the old driver is first removed and the new PHY driver is added.

This version configures the switch to have a CPU connected over an MII interface. It will enable PHY interfaces based on the MV88E61XX_PHY_PORTS macro. The switch is configured to allow PHY ports to only communicate to the CPU. This allows the switch to be used as a basic PHY on any/all ports.

This was developed on a board with an mv88e6176 connected over SGMII. It is intended to work with other configurations, but these could not be tested. Any testing on other configurations or with other mv88e61xx chips is appreciated.

Actually the driver was for the Wireless Space, which was removed but which I will resurrect as I did the Open-RDs. I will test the switch on the WS I have.

That's great. I'm currently reviewing the new driver and will appreciate the testing. I don't have any boards with this switch.

Thanks,

Could you please send me more info on the Wireless Space board? I would like something other than our custom board to test this on. I tried to get a Marvell RD-A370, but they are too expensive. I will be glad to add back in the command-line interface for configuring this board if it is needed to support your work.

Thanks for testing,
Kevin
