Subject: [PATCH v2 net-next 04/10] net: mscc: ocelot: change vcap to be compatible with full and quad entry
Date: Tue,  2 Jun 2020 13:18:22 +0800	[thread overview]
Message-ID: <20200602051828.5734-5-xiaoliang.yang_1@nxp.com> (raw)
In-Reply-To: <20200602051828.5734-1-xiaoliang.yang_1@nxp.com>

When calculating vcap data offset, the function only supports half key
entry. This patch modify vcap_data_offset_get function to calculate a
correct data offset when setting VCAP Type-Group to VCAP_TG_FULL or
VCAP_TG_QUARTER.
