[openib-general] [PATCH] [RFC] group devices by type

[Sean Hefty]

I'd like to get some feedback about adding the ability to group devices
by some higher level type.  This would permit identifying all devices
that are of type "Infiniband" from devices of other RDMA transports.

I've included the patch to ib_verbs.h to do this, along with changes to
mad.c to show how it would be used.  If this is okay, then similar changes
would be needed by a dozen or so other files, which I would do before
submitting a final patch.
