[lwip-devel] [patch #5834] Don't fragment flag

[Frédéric Bernon]

Follow-up Comment #17, patch #5834 (project lwip):

>so I think this should be a configurable option for each UDP or TCP
connection,

IP_DONTFRAGMENT would be the solution for you ? I think it's only useful to
do a "Path MTU discovery" (others uses seem to be difficult to integrate in
lwIP: handling ICMP messages, change mtu size per connection, etc...)

>possibly with a default setting which is configurable in lwipopts.h or
similar. 

I agree with you (comment #5), even if it's not to set a default value.

But I think Simon comment #16 is right. IP_REASSEMBLY is a good "solution". I
don't think to propose a patch for IP_DONTFRAGMENT, except if someone really
need it... But if you got one, please send, I will study it and integrate if
it's ok for others developers...
