Well, with an intro like that, how could I refuse?-)
In a nutshell, after repeated uses of the netperf UDP_STREAM test in
non-air-gapped test setups with link up/down testing and a default route
which pointed at the local "corporate/desktop/whathaveyou" network by QA
engineers who should have known better, taking-out things like security
camera video feeds, by default the data socket for a UDP_STREAM test is
set SO_DONTROUTE. This can be overridden with a test-specific -R 1 option.
This is not necessary if the test is UDP_RR or TCP_*.
