ISSI (Interface Step Sequence ID) defines the step sequence ID of the interface between the driver to the firmware and is incremented by steps of one. ISSI is used to enable deprecating/modifying features, command interfaces and such, while maintaining compatibility.
As the driver serves both ConnectIB (CIB) and ConnectX4, we carefully made sure that the IB functionality keeps running also on older CIB firmware releases that don't support ISSI. The Ethernet functionailty is available only on ConnectX4 where all firmware releases support the feature since the very basic ISSI level. So at this point no need for compatility code there. As done prior to this series, when the Ethernet functionlity is enabled, during the initialization flow, the core driver performs a query of the supported ISSIs using the QUERY_ISSI command, and then, if ISSI is supported, sets the actual issi value informing the firmware on which ISSI level to run, using SET_ISSI command. Previously, the IB driver wasn't ready to work on that mode, and hence building both the IB driver and the Ethernet functionality in the core driver were disallowed by Kconfigs, with this series, we allow users to enable them both.
