From 10e07f13c06690488087f5d3f2c59a9728def339 Mon Sep 17 00:00:00 2001 From: Matan Barak Date: Thu, 15 Oct 2015 18:38:54 +0300 Subject: [PATCH] IB/core: Remove smac and vlan id from path record 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.
