Date: Wed, 2 Mar 2022 11:29:29 +0800 From: Baowen Zheng <baowen.zheng@...igine.com> To: davem@...emloft.net, kuba@...nel.org Cc: xiyou.wangcong@...il.com, jhs@...atatu.com, netdev@...r.kernel.org, oss-drivers@...igine.com, simon.horman@...igine.com, roid@...dia.com Subject: [PATCH net-next v2] flow_offload: improve extack msg for user when adding invalid filter Add extack message to return exact message to user when adding invalid filter with conflict flags for TC action. In previous implement we just return EINVAL which is confusing for user.
