Subject: [PATCH net-next v12 1/8] net/sched: Rename user cookie and act cookie
Date: Wed, 15 Feb 2023 23:10:07 +0200 [thread overview]
Message-ID: <20230215211014.6485-2-paulb@nvidia.com> (raw)
In-Reply-To: <20230215211014.6485-1-paulb@nvidia.com>
struct tc_action->act_cookie is a user defined cookie,
and the related struct flow_action_entry->act_cookie is
used as an handle similar to struct flow_cls_offload->cookie.
Rename tc_action->act_cookie to user_cookie, and
flow_action_entry->act_cookie to cookie so their names
would better fit their usage.
Signed-off-by: Paul Blakey <paulb@nvidia.com>
