From: Suresh Reddy <redacted>

 From FW version 11.0 onwards, the FW supports a new "secure mode" feature
(based on a jumper setting on the adapter.) In this mode, the FW image when
flashed is authenticated with a digital signature. This patch logs
appropriate error messages and return a status to ethtool when errors
relating to FW image authentication occur.
