Forum Topic - "Dummy phy" for direct to Marvell switch?: (2 Items)
   
"Dummy phy" for direct to Marvell switch?  
Is there a way to create a "dummy PHY" for an MII-to-MII connection that goes directly to the switch? The switch is a 
Marvell 88E6717. We understand there are ways to revamp a device driver to work around the problem, but it would be nice
 if there was an easier way.

In my searches, I found the command line option "emu_phy" for one device driver. However there was no documentation 
describing it. 

This is with an IMX6, derived from a SabreLite board.

Thanks!
Re: "Dummy phy" for direct to Marvell switch?  
I have attached the source code for the emu_phy routines. All you have to
do is to point your mii_read() function to point to the emu_phy_read()
function and call the emu_phy_init() function when the driver starts. The
mii_write() function does nothing.
