Hello Nick, That's the spirit of my question: why couldn't you break up a CHDR packet over multiple Ethernet frames? I understand it is common for Ethernet to break up an IP packet (which would also have a 16-bits field for packet size in its header) into fragments, but limiting the size of the

That's the MTU of your network interface limiting the CHDR packet size. Can't break up CHDR packets over multiple network packets. Nick On Wed, Aug 1, 2018 at 11:25 AM Leandro Echevarría via USRP-users < usrp-users@lists.ettus.com> wrote: > Hey everybody, > > I'll somehow repeat a question I

Hey everybody, I'll somehow repeat a question I asked here a couple of months ago, to see again if I can get some guiding. Hope you understand: The CHDR packet length field in the CHDR header is 16 bits (i.e. 65536 bytes theoretical max length), but by doing Wireshark captures and playing with
