Subject: [PATCH net-next 08/10] ixgbe: Enable link management in E610 device
From: Piotr Kwapulinski <piotr.kwapulinski@...el.com>
Add high level link management support for E610 device. Enable the
following features:
- driver load
- bring up network interface
- IP address assignment
- pass traffic
- show statistics (e.g. via ethtool)
- disable network interface
- driver unload
