[PATCH 10/25] MBO: Add global operating class definitions
Ilan Peer
ilan.peer at intel.com
Mon Feb 15 06:53:32 PST 2016
From: Avraham Stern <avraham.stern at intel.com>
Add definitions for global operating classes. These definitions
will be used to construct supported operating classes
information element.
The operating classes definitions used locally for P2P module will be
removed and included in the general operating classes definitions.
