From: Jack Morgenstein Date: Fri, 3 Aug 2012 08:40:37 +0000 (+0000) Subject: IB/core: Reserve bits in enum ib_qp_create_flags for low-level driver use X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d2b57063e4a;p=linux-beck.git IB/core: Reserve bits in enum ib_qp_create_flags for low-level driver use Reserve bits 26-31 for internal use by low-level drivers. Two such bits are used in the mlx4_b driver SR-IOV implementation. These enum additions guarantee that the core layer will never use these bits, so that low level drivers may safely make use of them.
