[Intel-wired-lan] [next PATCH S94 04/13] i40e: Display message when entering and leaving recovery mode

[Alice Michael]

From: Filip Sadowski <filip.sadowski at intel.com>

This patch adds notification in dmesg when the driver detects the NIC
entered recovery mode. It also displays appropriate information when the
adapter leaves recovery mode restoring normal functionality.
