Considering that the data rate of the configuration specified at the scope is ~14Tbps, not really. Even the data rate that the scope is interpolating from is ~745Gbps, while 400Gbps Ethernet is still fairly rare and mostly limited to backbones.

assuming 3 packets, that's about 64MB of raw data per ethernet frame. The tshark output shows a 82 byte frame. That works out to 818400:1 overhead. Close to 1MB of .wfm data per 1 byte of packet data.
I suppose you could do some processing or compression closer to the input, but then you're just building a nic at that point.
Surprisingly cool going from raw IQ/analog data to ethernet frames much like the op has written.
