[lwip-devel] [patch #9384] Partial SACK (RFC 2018) support

[Simon Goldschmidt]

Follow-up Comment #25, patch #9384 (project lwip):

I've just pushed the patch with some cleanup additions by myself.

One question that I had while searching through the new code: is it really
allowed to remove a SACK we once sent? In other words: are we allowed to
remove OOSEQ segments we already SACKed or has the remote side freed them and
cannot retransmit them? This is probably covered by the spec, sorry I don't
have the time right now to look. Just wanted to write this here to not forget
it :-)
