Check out https://pipci.jeffgeerling.com/boards_cm https://pipci.jeffgeerling.com/boards_cm — there are a couple multi-port boards already in the works.
Also, if you go to the main page on that site, I have tested multiple multi-port PCIe cards, like a dual 2.5G card and a 4-port Intel i340, and all of them can be made to work without too much effort.
There are a few different things you can do with it, but in total, you'll be limited to about 3.2 (only through PCIe) to 4.2 Gbps (if also using the Pi's internal 1G ethernet) of internal bandwidth.

- geerlingguy 6y agoFull duplex as far as I can measure (in various scenarios). I'm still wrangling a couple PCIe switches that were giving me trouble previously, so I will definitely keep trying to get more than that!
