From 86cb13e4ec5060d94069a8418fd4f3ccb38edee2 Mon Sep 17 00:00:00 2001 From: Ido Schimmel Date: Mon, 25 Jul 2016 13:12:33 +0300 Subject: mlxsw: spectrum: Fix compilation error when CLS_ACT isn't set When CONFIG_NET_CLS_ACT isn't set 'struct tcf_exts' has no member named 'actions' and we therefore must not access it. Otherwise compilation fails. Fix this by introducing a new macro similar to tc_no_actions(), which always returns 'false' if CONFIG_NET_CLS_ACT isn't set.
