The 88E1111 has an MDIO interface and is accessed via the tse driver on power up. It should be noted that the phy is read for speed and duplex capability only upon initialization so that the driver can configure the tse to run at the minimum connection/duplex of the link/link-partner pair.

I have a RGMII interface tied to a switch chip with no MDIO between them and have modified the default duplex/connection speed to run at the rate that I am driving the RGMII bus with no issues.
