[PATCH net-next 01/15] igc: Call netif_queue_set_napi() with rtnl locked

[Tony Nguyen <anthony.l.nguyen@intel.com>]

From: Mika Westerberg <mika.westerberg@linux.intel.com>

When runtime resuming igc we get:

  [  516.161666] RTNL: assertion failed at ./include/net/netdev_lock.h (72)

Happens because commit 310ae9eb2617 ("net: designate queue -> napi
linking as "ops protected"") added check for this. For this reason drop
the special case for runtime PM from __igc_resume(). This makes it take
rtnl lock unconditionally.
