[dpdk-dev] [PATCH 6/7] netdev: Make netdev_set_mtu() netdev parameter non-const.

[Mark Kavanagh <mark.b.kavanagh@intel.com>]

From: Daniele Di Proietto <diproiettod@vmware.com>

Every provider silently drops the const attribute when converting the
parameter to the appropriate subclass.  Might as well drop the const
attribute from the parameter, since this is a "set" function.

Signed-off-by: Daniele Di Proietto <diproiettod@vmware.com>

v2->v1: add missing 'Signed-off-by' field in commit message.
