From aae0e68909bf2ef1b60d18c54105ab8b9c67c5a2 Mon Sep 17 00:00:00 2001 From: Codrin Ciubotariu Date: Tue, 15 Dec 2015 15:21:06 +0200 Subject: drivers: net: vsc9953: Add LAG support You can now configure LAG on VSC9953's ports using the command: ethsw [port ] aggr {[help] | show | } A port must belong to a single LAG. By default, a port belongs to a LAG equal to the port's number. For each frame, a hash will be calculated based on Source/Destination MAC addresses, Source/Destination IP(v4/v6) addresses, Source/Destination ports. This hash will be used to select a single egress port from LAG. This also assures that frames from the same flow will always have the same egress port.
