[ewg] [PATCH] ibdev2netdev: Support RNIC.

[Steve Wise]

The oldstyle=y logic in ibdev2netdev to match netdevs to ibdevs didn't
work for RNIC devices since their mac address is left justified in
the gid.  This patch uses the type attribute to do the right thing for
RNIC devices.  Note: the oldstyle=n logic works.
