From 8557cd74ca8af9a71ae19d445e33d92bd50a6dc5 Mon Sep 17 00:00:00 2001 From: Veaceslav Falico Date: Thu, 15 May 2014 21:39:59 +0200 Subject: bonding: replace SLAVE_IS_OK() with bond_slave_can_tx() They're verifying the same thing (except of IFF_UP, which is implied for netif_running(), which is also a prerequisite).
