Subject: [PATCH net-next 06/14] mlxsw: reg: Add max_shaper_bs to QoS ETS Element Configuration
Date: Fri, 24 Jan 2020 15:23:10 +0200	[thread overview]
Message-ID: <20200124132318.712354-7-idosch@idosch.org> (raw)
In-Reply-To: <20200124132318.712354-1-idosch@idosch.org>

From: Petr Machata <petrm@mellanox.com>

The QEEC register configures scheduling elements. One of the bits of
configuration is the burst size to use for the shaper installed on the
element. Add the necessary fields to support this configuration.
