Subject: [RFC PATCH net-next 2/4] netdevsim: Implement support for ethtool_ops::get_module_fw_info

From: Ido Schimmel <idosch@...dia.com>

For RFC purposes only, implement support for
ethtool_ops::get_module_fw_info.

A real implementation is expected to call CMIS common code (WIP) that
can be shared across all MAC drivers.
