From bd3606715effbf37df986548c43bbed0842b49d5 Mon Sep 17 00:00:00 2001 From: Eli Cohen Date: Mon, 14 Jul 2008 23:48:51 -0700 Subject: IPoIB: Use dev_set_mtu() to change mtu When the driver sets the MTU of the net device outside of its change_mtu method, it should make use of dev_set_mtu() instead of directly setting the mtu field of struct netdevice. Otherwise functions registered to be called upon MTU change will not get called (this is done through call_netdevice_notifiers() in dev_set_mtu()).
