Streaming data FPGA interface -> off the shelf?

This is the most recent I've found (my repo clones are kinda outdated).

Also, you might find derived code around all 'usbjtag' related source, at least for bulk transfers. All this code should compile with the license-free SDCC, I just remember some hickups with the migration to SDCC v3.

I can recommend you to have a look at the Ethernet cores from FPGA-Cores.com.
These are very easy to use and you get UDP / TCP and other stuff like remote programming, logic analyzer etc.
No charge for private projects. Free to download. I use them in almost all my projects.

Looks like these are RMII (10/100Mbit Ethernet), which is even slower than USB 2. Various methods can be ranked by their speed as follows:

USB 3 > Gigabit Ethernet > USB 2 > 100Mbit Ethernet

There are MII, RMII, GMII and RGMII so also Gigabit Ethernet.

For industrial application GigE or other Ethernet is good but the switch is some overhead and power over Ethernet is a thing but not as simple. I am going to take a look at the FTDI 16-bit FIFO chips in a bit more detail and see how far I get I think. My preliminary pick is 10M02SCM153 + FT600 -> connector. Sometimes I don't have time to really get into this stuff so we will see how far I get. This work isn't my highest priority but its somewhere on the list.
