From mboxrd@z Thu Jan 1 00:00:00 1970 From: Dennis Dalessandro Subject: [PATCH for-next 12/27] IB/core: Change port_attr.sm_lid from 16 to 32 bits Date: Fri, 04 Aug 2017 13:53:21 -0700 Message-ID: <20170804205320.17853.77236.stgit@scvm10.sc.intel.com> References: <20170804204842.17853.14858.stgit@scvm10.sc.intel.com> Mime-Version: 1.0 Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: 7bit Return-path: In-Reply-To: <20170804204842.17853.14858.stgit-9QXIwq+3FY+1XWohqUldA0EOCMrvLtNR@public.gmane.org> Sender: linux-rdma-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: dledford-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org Cc: linux-rdma-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, Don Hiatt , Ira Weiny , Dasaratharaman Chandramouli List-Id: linux-rdma@vger.kernel.org From: Dasaratharaman Chandramouli sm_lid field in struct ib_port_attr is increased to 32 bits. This enables core components to use larger LIDs if needed. The user ABI is unchanged and return 16 bit values when queried.
