Can an RMII phy be connected directly to another RMII phy
So it turns out an RMII Phy can talk to another RMII phy like this but the LAN9303 can't be connected directly to another LAN9303 as described.  The problem is that timing of the DV D0 and D1 signals coming out of one LAN9303 don't meet the requirements for DV D0 and D1 going into the other.  The data needs to be moved to the opposite clock edge for this approach to work.
