Subject: [RFC PATCH 05/11] IB/core: Change lid size in struct ib_wc from 16 to 32 bits
Date: Fri, 23 Sep 2016 13:44:28 -0400 [thread overview]
Message-ID: <1474652674-13110-6-git-send-email-ira.weiny@intel.com> (raw)
In-Reply-To: <1474652674-13110-1-git-send-email-ira.weiny-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>
From: Don Hiatt <don.hiatt-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>
lid field in ib_wc is increased to 32 bits. This enables core
components to use the larger addresses if needed.
The user ABI is unchanged and return 16 bit values when queried.
