Follow-up Comment #23, bug #20287 (project lwip):

Is everyone OK with using the last free bit of tcp_pcb->flags for remembering
a memory error in tcp_enqueue?

This is needed to fix nagle while still sending segments (in tcp_output) that
are incomplete due to memory restrictions (TCP_SND_BUF / TCP_SND_QUEUELEN or
empty pool).

Also, I chose to send anyway if a segment to be sent includes SYN, FIN or
RST, but I don't really know if that is necessary...

attaching the new patch

(file #14360)
