Otherwise, trying to use the socket buffers instead of BufReader/
BufWriter is doomed to overwhelm the application logic.

Calculate IP payload length from the total length field.
...
Before this commit, IP payload length was calculated by subtracting
the IP header length from the total underlying buffer length, which
fails if the underlying buffer has padding, e.g. like Ethernet
does.
