Subject: [PATCH net-next 10/11] selftests: mlxsw: Add scale test for tc-police
Date: Wed, 15 Jul 2020 11:27:32 +0300 [thread overview]
Message-ID: <20200715082733.429610-11-idosch@idosch.org> (raw)
In-Reply-To: <20200715082733.429610-1-idosch@idosch.org>
From: Ido Schimmel <idosch@mellanox.com>
Query the maximum number of supported policers using devlink-resource
and test that this number can be reached by configuring tc filters with
police action. Test that an error is returned in case the maximum number
is exceeded.
