Subject: [RFC/PATCH 07/18] ravb: Add magic_pkt to struct ravb_hw_info
Date: Thu, 23 Sep 2021 15:08:02 +0100 [thread overview]
Message-ID: <20210923140813.13541-8-biju.das.jz@bp.renesas.com> (raw)
In-Reply-To: <20210923140813.13541-1-biju.das.jz@bp.renesas.com>
E-MAC on R-Car supports magic packet detection, whereas RZ/G2L
do not support this feature. Add magic_pkt to struct ravb_hw_info
and enable this feature only for R-Car.
