I am working on vxworks os, about a project of network discovering.
When I try to send a broadcast message, from the vxworks target (option
SO_BROADCAST on my socket ).
I have never succeded in sending a packet longer than one mtu (1472
whithout header).
Have you ever seen this problem?
Why are these limitations?
Is it an error on the udp fragmentation?

Thanks for any help.
