@dpgeorge at micropython/micropython#2535 (comment) reported a strange issue that even though his wifi network interface has MTU of 1500, UDP packets larger than another known MTU value, 548, don't get thru to ESP8266. On my side, I didn't see such issue.

This issue was worked around by setting conservative data block size of each packet to 256: 6a395ad . Would be nice to understand what's happening there.
