[ofw] IB Hosts Name

[Alex Estrin]

As far as I can remember smi changes were related to mkey
security/verification.
I'm not sure of exact reason but sm mads with mkey = 0 ended up always
blocked from local processing.
So easy enough workaround is to configure your SM to use nonzero mkey
value.
This should get back host name in node description.
 
Thanks,
Alex

	WinOF used to behave like this, but some "improvement" in MAD
handling or some such broke that functionality.  It should be easy
enough for the SMI to trap node info responses (allowing the HCA to
perform all security checks) and replace the node description with the
host name.

	I notice that with the Linux OFED driver, the response to
'ibhosts' is the assigned name of the server, which is usually different
with every server. With the WinOF driver, the response to 'ibhosts' is
the name of the card, which is the same for every card.

	 

	Is it possible to have WinOF behave like OFED? I think it would
help with the management tools.

	 

	Thanks,
