[lwip-devel] [bug #20287] tcp_output_nagle sends too early

[Simon Goldschmidt]

Follow-up Comment #18, bug #20287 (project lwip):

This has taken some time, but finally, I found some free time to work on it
;-)

The main change is checking the nagle conditions in tcp_output in the last
while-loop (effectively calling tcp_output_segment only for 'full' segments or
on idle connections).

tcp_output_nagle remains defined as 'if(nagle_ok(pcb)) { tcp_output(pcb);}',
but can be omitted (at the cost of always calling tcp_output, which checks a
lot and then does nothing).
As a result, in the netconn API, I still use tcp_output_nagle.

As this is an integral part of the stack, I'd like you all to test it,
please, before I check it in!
