I am worried this might be a very stupid question, but is it possible for
a personalized application of gnuradio that I am developing, I change the
1500 (approximately) bytes limit on the payload before the packets get
fragmented. If it is possible, could you please give me few pointers. I am
not trying to do anything bad, just want to see if I can send my large
payload without any fragmentation and I understand this increases the
chances of errors.
I am assuming you’re talking about the USRP2 and the GigE interface?
The 1500 byte limit comes from Ethernet:
There are Jumbo Frames:
But I don’t know if the USRP2 hardware supports them.
To the real meat of the question - why do you feel you need to
transfer so much data in one shot? What are you transmitting that
1500 bytes doesn’t accomplish? Do you feel the USRP2 is not properly
receiving your packets?
What is the real purpose for wanting to overcome the 1500 byte limit?
