Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-04-11 This series contains updates to iflink, ixgbe and ixgbevf. The entire set of changes come from Vlad Zolotarov to ultimately add the ethtool ops to VF driver to allow querying the RSS indirection table and RSS random key. Currently we support only 82599 and x540 devices. On those devices, VFs share the RSS redirection table and hash key with a PF. Letting the VF query this information may introduce some security risks, therefore this feature will be disabled by default. The new netdev op allows a system administrator to change the default behaviour with "ip link set" command. The relevant iproute2 patch has already been sent and awaits for this series upstream. ====================
