[lwip-users] UDP-based reliable bulk data transfer

I need to send large quantities of data reliably from a Zynq-based device to
a PC.
I'm looking for a data transfer protocol which can get as close as possible
to wire speed on a dedicated 1Gb ethernet link. It would be nice although
not strictly required it it worked over arbitrary internet connections.

Currently I'm considering either porting http://enet.bespin.org/ or
http://udt.sourceforge.net/ to lwIp or rolling my own UDP-based protocol. I
will need support for zero-copy with scatter-gather DMA.

Has anyone done this before? Any suggestions?
