8c7c723dfe net/sfc/base: import MAC statistics
MAC statistics are either periodically (if supported/requested)
or on-demand written to provided DMA-mapped memory.
If periodic update is not supported (e.g. for EF10 virtual
functions), it is the driver responsibility to handle it.

EFSYS_OPT_MAC_STATS should be enabled to use it.

6f619653b9 net/sfc/base: import MCDI implementation
Implement interface to talk to NIC management CPU. Provide
helpers to fill in MCDI requests, execute it and process
received response.

MCDI request is prepared in either PCI BAR mapped memory
(SFN5xxx/SFN6xxx) or DMA-mapped memory (SFN7xxx/SFN8xxx) and,
doorbell is pressed (memory-mapped register) to execute it.

Events about MCDI completion are delivered to house-keeping
event queue, but usage of these events is optional and MCDI
buffer may be simply polled waiting for completion
indication set.

19b64c6ac3 net/sfc/base: import libefx base
libefx is a platform-independent library to implement drivers
for Solarflare network adapters. It provides unified adapter
family independent interface (if possible).

Driver must provide efsys.h header which defines options
(EFSYS_OPT_*) to be used and macros/functions to allocate
memory, read/write DMA-mapped memory, read/write PCI BAR
space, locks, barriers etc.

efx.h and efx_types.h provide external interfaces intended
to be used by drivers. Other header files are internal.
