Subject: [PATCH net-next 5/5] selftests: mlxsw: Add Spectrum-2 target scale for tc flower scale test
Date: Thu, 17 Oct 2019 09:55:18 +0300	[thread overview]
Message-ID: <20191017065518.27008-6-idosch@idosch.org> (raw)
In-Reply-To: <20191017065518.27008-1-idosch@idosch.org>

From: Danielle Ratson <danieller@mellanox.com>

Return the maximum number of tc flower filters that can be offloaded.
Currently, this value corresponds to the number of counters supported by
the driver.
