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

[Frédéric Bernon]

Follow-up Comment #9, patch #5834 (project lwip):

In "RFC 791 - Internet Protocol", we can read :

"If the Don't Fragment flag (DF) bit is set, then internet fragmentation of
this datagram is NOT permitted, although it may be discarded.  This can be
used to prohibit fragmentation in cases where the receiving host does not
have sufficient resources to reassemble internet fragments."

When I read the "can be used", I think "is not per default". 


Ok to disable IP_DF ?

(just for information, read that, it's an good paper on fragmentation subject
