Subject: [RFC v3 net-next 10/10] qede: Add basic ethtool support

From: Sudarsana Kalluru <Sudarsana.Kalluru@...gic.com>

This adds basic ethtool operations to the qed driver, allowing support in:
 - Statistics gathering [ethtool -S]
 - Setting of debug level [ethtool -s <interface> msglvl]
 - Getting basic information [ethtool, ethtool -i]

In addition it adds the ability to change the MTU.
