Note that it has some problems with reading the final few bytes. It completely failed when I set buffer size to 15000. It seems that only some particular buffer sizes result in successful transfer, powers of two or whatever.

Yep, I have a couple of those boards and they are fine.  And getting 45 MB/s should not be a problem at all.
Can you measure the distance between the headers on the board? I already ordered it but it still didn't arrive.

If this is just a hack consider a Gigabit Ethernrt PHY, spewing UDP packets  Add a sequence number in the header to detect lost packets.

If you can use a dev board that already has this for you it should be easy

I don't have only have Gigabit ethernet or USB 3, so looks like USB 2 is the only option
