	Great! just pull the repository.

I noticed the new "hostnames are mandatory police" kick in:

bash-3.2$ ./netperf-wrapper --list-tests
Available tests:
  cisco_5tcpup               :  RTT Fair Realtime Response Under Load
  cisco_5tcpup_2udpflood     :  Cisco 5TCP up + 2 6Mbit UDP
Error occurred: No hostname specified.

Maybe you could allow listing the tests without a hostname?

	Anyway., just ran the rrul_be test from my macbook to cerowrt and I still see the massive bias for upload of around 10:1, same as with rrul and rrul_coclassification, and tcp_bidirectional. When I ran tcp_bidirectional on the universities wireless network (the only test that actually runs there), I get larger downloads than uploads. Wireless is weird...


Best
	Sebastian
