Date: Wed, 22 Sep 2021 19:03:37 -0700 From: Colin Foster <colin.foster@...advantage.com> To: netdev@...r.kernel.org, linux-kernel@...r.kernel.org Cc: Vladimir Oltean <vladimir.oltean@....com>, Claudiu Manoil <claudiu.manoil@....com>, Alexandre Belloni <alexandre.belloni@...tlin.com>, UNGLinuxDriver@...rochip.com, "David S. Miller" <davem@...emloft.net>, Jakub Kicinski <kuba@...nel.org> Subject: [PATCH v1 net 0/1] net: mscc: ocelot: broadcast storm fixup Ocelot ports would still forward out ethernet broadcasts when they were in the LEARNING or BLOCKING state. This is due to the ocelot_get_bridge_fwd_mask, which would tell disabled ports to forward packets out all FORWARDING ports. Broadcast storms would insue. This patch restores the functionality of disabling forwarding for ports that aren't in the FORWARDING state. No more broadcast storms. Tested and verified on an in-development driver, and Vladimir has done independent testing and verification on supported hardware.
