Subject: [PATCH v8 net-next 02/13] flow_offload: reject to offload tc actions in offload drivers
Date: Fri, 17 Dec 2021 19:16:18 +0100 [thread overview]
Message-ID: <20211217181629.28081-3-simon.horman@corigine.com> (raw)
In-Reply-To: <20211217181629.28081-1-simon.horman@corigine.com>
From: Baowen Zheng <baowen.zheng@corigine.com>
A follow-up patch will allow users to offload tc actions independent of
classifier in the software datapath.
In preparation for this, teach all drivers that support offload of the flow
tables to reject such configuration as currently none of them support it.
