Subject: RE: [PATCH] IB/CMA: Initialize hop_limit to a known default macro
instead of 1 as is done currently.

This is not an IPv6 route though. AFAIK, RoCE/IBoE is not routable, so the hop
limit should be set to 1. Using a different value affects timeout values set
by the IB CM.
Can you describe more of the reasoning behind this change?
Sean,
This change was done precisely to enable us to do that i.e make it
routable. This was the only suitable macro i could find that defines a certain
default value for the hop limit and is used by the IPv6 layer in the kernel
already. I'm open to other suggestions of values, but pegging to 1 means we are
not allowing any scope for it to be routable in the future ..Would you agree ?
Thanks
Som
