From 165779231ff9e9c4ac7baaee84eff91d589f3e22 Mon Sep 17 00:00:00 2001 From: Shmulik Ladkani Date: Thu, 13 Oct 2016 09:06:41 +0300 Subject: [PATCH] net/sched: act_mirred: Rename tcfm_ok_push to tcfm_mac_header_xmit and make it a bool 'tcfm_ok_push' specifies whether a mac_len sized push is needed upon egress to the target device (if action is performed at ingress). Rename it to 'tcfm_mac_header_xmit' as this is actually an attribute of the target device (and use a bool instead of int). This allows to decouple the attribute from the action to be taken.
