Subject: [PATCH 1/4] net/hns3: restrict FDIR only support one tunnel header
Date: Fri, 18 Oct 2024 14:19:38 +0800 [thread overview]
Message-ID: <20241018061941.29960-2-haijie1@huawei.com> (raw)
In-Reply-To: <20241018061941.29960-1-haijie1@huawei.com>
From: Chengwen Feng <fengchengwen@huawei.com>
The device's flow director supports a maximum of one tunnel header, if
passed more than one tunnel header from rte-flow API, the driver should
return error.
