[lwip-devel] [bug #26672] close connection when receive window = 0

[Simon Goldschmidt]

Follow-up Comment #1, bug #26672 (project lwip):

This is a bit tricky: I'd suggest draining the recvmbox/acceptmbox from
netconn_delete before calling do_delconn. This would mean that after a call to
lwip_close/netconn_delete, no more data can be received, but that's what we
want.

I'd add a new function netconn_drain, that drains and frees conn->recvmbox
and conn->acceptmbox while calling tcp_recved() and tcp_accepted() so that the
counters are correct afterwards.
