From mboxrd@z Thu Jan 1 00:00:00 1970 From: Matan Barak Subject: [PATCH for-next V1 10/10] IB/core: Remove smac and vlan id from path record Date: Fri, 7 Aug 2015 16:01:03 +0300 Message-ID: <1438952463-23707-11-git-send-email-matanb@mellanox.com> References: <1438952463-23707-1-git-send-email-matanb@mellanox.com> Return-path: In-Reply-To: <1438952463-23707-1-git-send-email-matanb-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org> Sender: linux-rdma-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: Doug Ledford Cc: linux-rdma-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, Matan Barak , Jason Gunthorpe , Or Gerlitz , Haggai Eran , Somnath Kotur List-Id: linux-rdma@vger.kernel.org The GID cache accompanies every GID with attributes. The GID attributes link the GID with its netdevice, which could be resolved to smac and vlan id easily. Since we've added the netdevice (ifindex and net) to the path record, storing the L2 attributes is duplicated data and hence these attributes are removed.
