Subject: [net-next 6/6] ixgbe: check for WoL support in single function
From: Jacob Keller <jacob.e.keller@...el.com>
This patch consolidates the case logic for checking whether a device supports
WoL into a single place. Previously ethtool and probe used similar logic that
was copied and maintained separately. This patch encapsulates the core logic
into a function so that a user only has to update one place.
