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.

The TX DMA engine issues upstream read requests when there is room in
the TX FIFO for the completion. However, the fetches for the rest of
the packet might be delayed by any back pressure. Since a flush must
wait for an EOP, the entire flush may be delayed by back pressure.
Mitigate this by disabling flow control before the flushes are
started. Since PF and VF flushes run in parallel introduce
fc_disable, a reference count of the number of flushes outstanding.

would bring with it its own testing.

When SR-IOV is enabled we may receive FLR (Function-Level Reset)

Currently we stop interrupt-driven event processing before flushing RX

flush events and discards any others it finds. Change it to work with
the regular event handling functions.
