From: Sudarsana Kalluru <sudarsana.kall...@qlogic.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.
