Subject: igb: reset the PHY before reading the PHY ID
From: Aaron Sierra <asierra(a)xes-inc.com>
[ Upstream commit 182785335447957409282ca745aa5bc3968facee ]
Several people have reported firmware leaving the I210/I211 PHY's page
select register set to something other than the default of zero. This
causes the first accesses, PHY_IDx register reads, to access something
else, resulting in device probe failure:
igb: Intel(R) Gigabit Ethernet Network Driver - version 5.4.0-k
igb: Copyright (c) 2007-2014 Intel Corporation.
igb: probe of 0000:01:00.0 failed with error -2
This problem began for them after a previous patch I submitted was
applied:
commit 2a3cdead8b408351fa1e3079b220fa331480ffbc
Author: Aaron Sierra <asierra(a)xes-inc.com>
Date: Tue Nov 3 12:37:09 2015 -0600
igb: Remove GS40G specific defines/functions
I personally experienced this problem after attempting to PXE boot from
I210 devices using this firmware:
Intel(R) Boot Agent GE v1.5.78
Copyright (C) 1997-2014, Intel Corporation
Resetting the PHY before reading from it, ensures the page select
register is in its default state and doesn't make assumptions about
the PHY's register set before the PHY has been probed.

Similar to ixgbe, when an interface is part of a namespace it is
possible that igb_close() may be called while __igb_shutdown() is
running which ends up in a double free WARN and/or a BUG in
free_msi_irqs().
Extend the rtnl_lock() to protect the call to netif_device_detach() and
igb_clear_interrupt_scheme() in __igb_shutdown() and check for
netif_device_present() to avoid calling igb_clear_interrupt_scheme() a
second time in igb_close().
Also extend the rtnl lock in igb_resume() to netif_device_attach().
