From 03ea01e9db82203e83b306b6c61d2cc9f0da4199 Mon Sep 17 00:00:00 2001 From: Ido Schimmel Date: Tue, 23 May 2017 21:56:30 +0200 Subject: [PATCH] mlxsw: spectrum_router: Adjust RIF configuration for new firmware versions In new firmware versions, when configuring a {Port, VID} as a router interface, the driver is responsible for enabling the STP filter and disabling learning. Otherwise, packets are discarded. This change doesn't break existing firmware versions, but is required for newer firmware versions.
