Greetings,
I am writing a video transmitter. The protocol I am using requires that a "test
packet" has its do not fragment bit set. This is used to determine the maximum
usable MTU of the intervening network nodes.
I would like to know the recommended method for setting this bit in my UDP
transmission. I am currently using the ip_output_if() function, and it does not
have any arguments to allow this.
Regards,
Roger W. Cover
