Subject: [PATCH net-next 7/7] selftests: mlxsw: Add a test case for devlink-trap
Date: Wed, 21 Aug 2019 10:19:37 +0300 [thread overview]
Message-ID: <20190821071937.13622-8-idosch@idosch.org> (raw)
In-Reply-To: <20190821071937.13622-1-idosch@idosch.org>
From: Ido Schimmel <idosch@mellanox.com>
Test generic devlink-trap functionality over mlxsw. These tests are not
specific to a single trap, but do not check the devlink-trap common
infrastructure either.
Currently, the only test case is device deletion (by reloading the
driver) while packets are being trapped.
