ethtool: Add an interface for flashing transceiver modules' firmware
CMIS compliant modules such as QSFP-DD might be running a firmware that can be updated in a vendor-neutral way by exchanging messages between the host and the module as described in section 7.3.1 of revision 5.2 of the CMIS standard. Add a pair of new ethtool messages that allow: * User space to trigger firmware update of transceiver modules * The kernel to notify user space about the progress of the process The user interface is designed to be asynchronous in order to avoid RTNL being held for too long and to allow several modules to be updated simultaneously. The interface is designed with CMIS compliant modules in mind, but kept generic enough to accommodate future use cases, if these arise.
