From 7dcc9d8a40f85cbd76acdebcc45ccdfe4a84337f Mon Sep 17 00:00:00 2001 From: Edward Cree Date: Mon, 7 Sep 2020 17:14:20 +0100 Subject: [PATCH] sfc: don't double-down() filters in ef100_reset() dev_close(), by way of ef100_net_stop(), already brings down the filter table, so there's no need to do it again (which just causes lots of WARN_ONs). Similarly, don't bring it up ourselves, as dev_open() -> ef100_net_open() will do it, and will fail if it's already been brought up.
