TCP loopback breaks at high bandwidth #28

Closed apsun closed 2 years ago

Terminal 1: nc -l 127.0.0.1 1111 Terminal 2: nc 127.0.0.1 1111 < random

Socket manages to send some data, then aborts the connection. Adding TCP_DEBUG_PRINT=1 interestingly makes it work fine, so this could be something related to TCP windows or ne2k capacity.

No idea why I thought ne2k had anything to do with it, this is loopback
