Subject: [PATCH iwl-next v6 1/7] ixgbe: Add support for E610 FW Admin Command Interface
Add low level support for Admin Command Interface (ACI). ACI is the
Firmware interface used by a driver to communicate with E610 adapter. Add
the following ACI features:
- data structures, macros, register definitions
- commands handling
- events handling
