Add malicious driver detection to ixgbe driver. The supported devices are E610 and X550. Handling MDD events is enabled while VFs are created and turned off when they are disabled. There is no runtime command to enable or disable MDD independently. MDD event is logged when malicious VF driver is detected. For example VF can try to send incorrect Tx descriptor (TSO on, but length field not correct). It can be reproduced by manipulating the driver, or using driver with incorrect descriptor values. Example log: "Malicious event on VF 0 tx:128 rx:128" Reviewed-by: Przemek Kitszel <przemyslaw.kitszel@intel.com> Reviewed-by: Jedrzej Jagielski <jedrzej.jagielski@intel.com> Reviewed-by: Marcin Szycik <marcin.szycik@linux.intel.com> Signed-off-by: Paul Greenwalt <paul.greenwalt@intel.com> Signed-off-by: Michal Swiatkowski <michal.swiatkowski@linux.intel.com> Reviewed-by: Simon Horman <horms@kernel.org> Tested-by: Rafal Romanowski <rafal.romanowski@intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com>
