I am getting this right, the W5500 acts as an Ethernet bridge ?

Yes

So this should also work with the 7I90HD in spi mode ?

7I90HD should work with small changes

Or any Mesa SPI firmware (custom) like something I've put together ?

No,
This has nothing to do with the Mesa gateware/firmware; RIO runs on Mesa hardware here.
Mesa gateware does not support W5500 modules.

So basically you're supporting Mesa hardware, something I mentioned along time ago, which the Spartan6 hardware I added to the repo basically is, 7c81 ish clone.

Exactly, and now I also have an original mesa board with which I was able to create a board file and test the whole thing.

OK, there only dif in mine clone was the SPI & FPGA clk pins. Seemed to be very picky regarding that.

Any code in the repo yet ?

github.com/multigcs/riocore/tree/dev/riocore/boards/Mesa7c81

Can't believe I missed it.
