[lwip-devel] [patch #5779] Tunning TCP KeepAlives values

[Frédéric Bernon]

Follow-up Comment #2, patch #5779 (project lwip):

To my point of view, these constants have the same "internal" level than
TCP_SYNMAXRTX, TCP_MAXRTX, etc...

So, give the possibility to Lwip users to change these constants is only to
give the possibility to do a "system level settings".

What you propose give a "socket level settings", but need to have more code
(but you're right, it's a better solution - in functionnality). Onyl problem
I see: these options are not really "universal" (Winsock applications don't
use them).

As I propose it, the patch is simple, and "source code compatible" : if
someone get the last CVS release, he doesn't have to change anything in this
code, the behavior is the same. And the footprint doesn't change.

So, this change is really minor, and doesn't affect others users.
