Subject: [2.6 patch] cleanup congestion control options
This patch contains the following cleanups:
- note in the prompt if an option depends on EXPERIMENTAL
- remove "default n"s that didn't have any effect
- remove "default m"s from options under TCP_CONG_ADVANCED:
if you manually choose congestion control modules you should
know which ones you want
