Being able to debug connectivity problems at the IB level strikes me 
as very useful. Perhaps some people expect to always use IPoIB on 
their IB network, and therefore plan to use IP tools. Even in these 
configurations, native IB protocols would be useful if IPoIB wasn't 
working.

It looks like you modeled the ECHO and TIMESTAMP formats after their 
ICMP counterparts. The TIMESTAMP type appears to have been dropped 
from ICMPv6. Do you know why?
