Subject: [PATCH v2 net-next 5/5] selftests: net: bridge: Parameterize ageing timeout
Date:   Thu,  3 Feb 2022 11:16:57 +0100
Message-Id: <20220203101657.990241-6-tobias@waldekranz.com>

Allow the ageing timeout that is set on bridges to be customized from
forwarding.config. This allows the tests to be run on hardware which
does not support a 10s timeout (e.g. mv88e6xxx).
