[SR-Users] don't fragment flag in rtpengine request

[Juha Heinanen]

i was wondering why sometimes requests to rtpengine don't get through
and icmp unreachable destination error message is received.  it turned
out that in these error cases ip packet containing the rtpengine request
has 0x02 (don't fragment) flag set even when the packet was bigger than
4 KB.  in this case kamailio was running in an amazon container which
may be doing something weird.

is it somehow possible from the application (= kamailio) to control
setting of that flag?
