IMO, more of the issues with these advanced networking protocols is latency - something that is usually more addressable via protocol dev than just hardware. Would be very interesting to see nVidia try to acquire Xilinx and supercharge their "Aurora" low overhead transfer protocol...

Is it, really?
FPGA's are now all over HPC, the 5G rollout is going to put a LOT of really expensive FPGA's in new towers, and high-end networking gear is about to get a bump due to PCI going up.
I don't know how much damage the Intel acquisition did to Altera, but if Altera has been AWOL with big customers due to the Intel acquisition, Xilinx may have a massive amount of customer wins locked in for a very long time.
I wish Xilinx would die in a hot flaming pit of Hell for many and various reasons, but they are the 500lb gorilla of FPGAs.
My original comment reacted to nVidia acquiring Xilinx and I am trying to explain why that won't happen: it's too expensive.
