From: Matan Barak Date: Thu, 15 Oct 2015 15:38:54 +0000 (+0300) Subject: IB/core: Remove smac and vlan id from path record X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=10e07f13c06690488087f5d3f2c59a9728def339;p=linux.git 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.
