Subject: [PATCH 21.11 17/17] net/hns3: add verification of RSS types
Date: Tue, 21 Mar 2023 17:23:06 +0800 [thread overview]
Message-ID: <20230321092306.16918-18-lihuisong@huawei.com> (raw)
In-Reply-To: <20230321092306.16918-1-lihuisong@huawei.com>
[ upstream commit eb3ef9e0d7eb54b47ab58d3d14f9f5fff3f4120b ]
Add the verification of RSS types from ethdev ops and rte flow without
pattern attribute. The following cases are invalid:
1. types contains unsupported RSS type but hasn't type driver support.
2. types has L3 src/dst but hasn't supported packet type.
3. types has L4 src/dst but hasn't supported packet type and hasn't IP
packet type.
