Can we move the programs and create a dependency from them back to networking? Perhaps shared components like udpgso_* need to live under tools/net so they can be easily "depended on"? Either that or they need to switch to a different traffic generator for the BPF test, cause there's more networking selftests using the UDP generators :(
