Instead of using a global lock, the PCIe transport
can use an own lock for its IRQ. This will make it
possible to not disable IRQs for the shared lock.
The lock is currently used throughout the code but
this can be improved even further by splitting up
the locking for the queues.

In order to separate the different parts of the
driver better, we are reducing the shared data.
This moves the workqueue to "priv", and removes
it from the transport. To do this, simply use
schedule_work() in the transport.

Replaced the old SRAM and periphery indirect access functions
with a unified indirect memory access functions. These include
new IWL_TM_CMDs for buffer read/write/dump which replace the
SRAM read/dump commands, but the API for IWL_TM_CMD_INDIRECT_REG
read/write will now not be supported (returns error).
This also handles writing to periphery registers in 1-3 bytes.

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.

Abstract some of the channel operations to allow for 'extra'
channels that do not have RX or TX queues.
- Try to assign a channel to each extra channel type that is enabled
for the NIC, but gracefully degrade if we can't allocate sufficient
MSI-X vectors
- Allow each extra channel type to generate its own channel name
- Allow channel types to disable reallocation and reinitialisation
of their channels

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.
The same principle could be applied to Falcon, but that
would bring with it its own testing.

For SR-IOV we will need to send events to event queues that belong to
VFs serviced by other drivers. Change the parameters of
efx_generate_event() to allow this and declare it extern.
While we're at it, remove the existing declaration under the wrong
name efx_nic_generate_event().

When SR-IOV is enabled we may receive FLR (Function-Level Reset)
events, associated queue flush events and requests from VF drivers at
any time. Therefore we need to keep event queues and interrupts
enabled whenever possible.
Currently we stop interrupt-driven event processing before flushing RX
and TX queues; efx_nic_flush_queues() then polls event queues for
flush events and discards any others it finds. Change it to work with
the regular event handling functions.
Currently efx_start_channel() fills RX queues synchronously when a
device is brought up. This could now race with NAPI, so change it to
send fill events.
This was almost entirely written by Steve Hodgson, formerly
shodgson@solarflare.com.

The RMFT_DEST_MAC and TMFT_SRC_MAC register fields were previously
documented as 44 bits wide, whereas a MAC address has 48 bits.
Thankfully the hardware uses the correct width and the driver has
used separate definitions that divide each of these into 32-bit and
16-bit fields.
Fix the initial definitions for these fields and rewrite the latter
definitions to use them.

On Siena each TX queue can be configured to send only packets for
which there is a TX MAC filter that matches the source MAC address,
queue ID, and optionally VID. This will be used to implement the
'spoofchk' feature for SR-IOV virtual functions.

On Siena all received packets that don't match a more specific filter
will match the unicast or multicast default filter. Currently we
leave these set to the default values (RSS with base queue number of
0). Allow them to be reconfigured to select a single RX queue.
These default filters are programmed through the FILTER_CTL register,
but we represent them internally as an additional table of size 2.
