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

[Simon Goldschmidt]

Follow-up Comment #12, patch #9384 (project lwip):

Re comment #10:
> Would it make more sense to have a MEMP_SACK_BLOCK? 

Not a bad idea. However what I dislike about it is that we can come into a
situation where we fail to allocate such a SACK region. Memp allocation might
be slower than using the array, but all that array-moving code is not fast,
either...

However, the idea of somehow combining the ooseq list with the SACK list
*does* make sense! Maybe we could think more about it in that direction.
