[lwip-devel] [task #7040] Work on tcp_enqueue

[Jakob Stoklund Olesen]

Follow-up Comment #14, task #7040 (project lwip):

OK, second attempt: The attached patch tcp-enqueue-split splits tcp_enqueue
into two separate functions for data and options.

This patch is against CVS HEAD and replaces the previous tcp-enqueue-concat
patch.

- tcp_enqueue_data does proper TCP segmentation.

- tcp_enqueue_data has static linkage and will be inlined in tcp_write by a
savvy compiler.

- tcp_enqueue_options fixes a bug where sending a FIN with snd_buf==0 would
underflow snd_buf.

This change increases the tcp_out code size from 5356 to 5616 bytes on a
Blackfin.
