Ben Hutchings 0a6e5008a9 sfc: Fix MCDI structure field lookup
The least significant bit number (LBN) of a field within an MCDI
structure is counted from the start of the structure, not the
containing dword.  In MCDI_ARRAY_FIELD() we need to mask it rather
than using the usual EFX_DWORD_FIELD() macro.

Stuart Hodgson c3cba721f1 sfc: Allow efx_mcdi_rpc to be called in two parts
For NIC/System time synchonisation efx_mcdi_rpc needs to be split in
efx_mcdi_rpc_start and efx_mcdi_rpc_finish operations.

Ben Hutchings cd2d5b529c sfc: Add SR-IOV back-end support for SFC9000 family
On the SFC9000 family, each port has 1024 Virtual Interfaces (VIs),
each with an RX queue, a TX queue, an event queue and a mailbox
register.  These may be assigned to up to 127 SR-IOV virtual functions
per port, with up to 64 VIs per VF.

We allocate an extra channel (IRQ and event queue only) to receive
requests from VF drivers.

There is a per-port limit of 4 concurrent RX queue flushes, and queue
flushes may be initiated by the MC in response to a Function Level
Reset (FLR) of a VF.  Therefore, when SR-IOV is in use, we submit all
flush requests via the MC.

The RSS indirection table is shared with VFs, so the number of RX
queues used in the PF is limited to the number of VIs per VF.

This is almost entirely the work of Steve Hodgson, formerly
shodgson@solarflare.com.

Ben Hutchings 55c5e0f85d sfc: Add hwmon driver for boards using SFC9000-family controllers
The SFC9000-family controllers have firmware to manage all board
peripherals including temperature, heat sink continuity and voltage
sensors.  The firmware reports sensor alarms, which we log, and
will shut down the board if necessary.

Some users may want to monitor their boards more closely, so add an
hwmon driver that exposes all sensors reported by the firmware.  Move
efx_mcdi_sensor_event() into the new file so it can share the array of
sensor labels with the hwmon driver.

Ben Hutchings 710b208dc2 sfc: Merge efx_mac_operations into efx_nic_type
No NICs need to switch efx_mac_operations at run-time, and the MAC
operations are fairly closely bound to NIC types.

Move efx_mac_operations::reconfigure to efx_nic_type::reconfigure_mac
and efx_mac_operations::check_fault fo efx_nic_type::check_mac_fault.
Change callers to call through efx->type or directly if the NIC type
is known.

Remove efx_mac_operations::update_stats.  The implementations for
Falcon used to fetch MAC statistics synchronously and this was used by
efx_register_netdev() to clear statistics after running self-tests.
However, it now only converts statistics that have already been
fetched (and that only for Falcon), and the call from
efx_register_netdev() has no effect.
