Need to implement a 2-port switch on a custom module and as the CMSIS 'Ethernet MAC' has been the cleanest/easiest to implement given the 3 choices (Keil, CycloneTCP, or lwIP) I would like to know of any potential gotchas before moving forward with this design. I noticed that all 'Ethernet PHY' selections and the 'Ethernet' selection are all single-port hardware. Anyone use a 2-port switch and the CMSIS pack in this manner?
