Actually they are quite different. When we assert flow control, we flow control _everything_ upstream between the USRP2 and the host. Unless you want your network to die, die, die, don't put a switch between the USRP2 and the host if you are transmitting, and for sure, don't plug anything else into the switch. You may find corner cases where it might work, but it's highly dependent on what kind of switch, how much buffering it has, how the switch was instructed to negotiate flow control etc. There are big portions of the Internet universe that consider it "evil" for an end point to assert flow control. That's what we do. For all the gory details on this, see a good reference on Gigabit ethernet flow control. I found Rich Seifert's, "Gigabit Ethernet: Technology and Applications for High-Speed LANS" useful. You could also read the GigE ethernet spec.
