Description Tommaso Pecorella 2013-06-25 16:45:04 UTC

A node will try to self-send ICMP_TOO_BIG if a packet is larger than the MTU.
The result is pretty annoying (crash and/or packets not being sent).

Fixed in changeset:   9855:d478e8a3b66e

The node should check if it's the origin of the packet. If so, the packet should be fragmented (instead of replying with ICMP_TOO_BIG)
