I want to extend my i.MX6 Quad Board with multiple Ethernet ports.

I need in minimum one BroadR-Reach port and one standard 100Base-T Ethernet port. Therefor I thought to take the NXP SJA1105 with a TJA1100 PHY and a KSZ8081 PHY. The SJA1105  should connect over RGMII with the i.MX6Q.


Is it possible to connect Automotiv Ethernet PHY and Ethernet PHY to the SJA1105 in mixture mode? In that constallatoin I also have a mediaconverter between Automotive Ethernet and Ethernet.
