Subject: [PATCH net-next v2 3/8] ravb: Add num_gstat_queue to struct ravb_hw_info
Date: Mon,  2 Aug 2021 11:26:49 +0100	[thread overview]
Message-ID: <20210802102654.5996-4-biju.das.jz@bp.renesas.com> (raw)
In-Reply-To: <20210802102654.5996-1-biju.das.jz@bp.renesas.com>

The number of queues used in retrieving device stats for R-Car is 2,
whereas for RZ/G2L it is 1.

Add the num_gstat_queue variable to struct ravb_hw_info, to add subsequent
SoCs without any code changes to the ravb_get_ethtool_stats function.
