Subject: [patch net-next 04/20] net: sched: use tc_setup_cb_call to call per-block callbacks

From: Jiri Pirko <[email-masked]>
Date: Tue, 17 Oct 2017 22:05:59 +0200

From: Jiri Pirko <[email-masked]>

Extend the tc_setup_cb_call entrypoint function originally used only for
action egress devices callbacks to call per-block callbacks as well.
