Subject: [net-next v2 07/14] ice: save PCI state in probe
Date: Wed,  6 Nov 2019 11:37:49 -0800	[thread overview]
Message-ID: <20191106193756.23819-8-jeffrey.t.kirsher@intel.com> (raw)
In-Reply-To: <20191106193756.23819-1-jeffrey.t.kirsher@intel.com>

From: Michal Swiatkowski <michal.swiatkowski@intel.com>

Save state to correct recovery memory and I/O BARs address
after PCI bus reset. Without this after reset kernel can't
read device registers.
