Use a linked list to associate user-facing context IDs with FW-facing
context IDs (since the latter can change after an MC reset).

8000 series adapters support filtering VXLAN, NVGRE and GENEVE traffic
based on inner fields, and when the NIC recognises such traffic, it
does not match unencapsulated traffic filters any more. So add catch-
all filters for encapsulated traffic on supporting platforms.
Although recognition of VXLAN and GENEVE is based on UDP ports, and thus
will not occur until the driver (on the primary PF) notifies the
firmware of UDP ports to use, NVGRE will always be recognised, hence
without this patch 8000 series adapters will drop all NVGRE traffic.
Partly based on patches by Jon Cooper <jcooper@solarflare.com>.

MAC filters inserted automatically by the driver, based on the device
address list (EF10) or no-match filters (Siena), should be overridable
at MANUAL or REQUIRED priority. Currently they themselves have
REQUIRED priority and this requires some odd special-casing.
We also can't reliably tell whether such a MAC filter has or has
not been overridden. We just remember that it is wanted by the
stack (RX_STACK flag).
Add another priority level, AUTO, between HINT and MANUAL, and
use this for the automatic filters while they have not been
overridden. Remove the RX_STACK flag. Add an RX_OVER_AUTO
flag which is set only when an AUTO filter has been overridden
(or was requested to be inserted while a higher-priority filter
existed).

Update the dates for files that have been added to in 2012-2013.
Drop the 'Solarstorm' brand name that's still lingering here.

MAC filters inserted on request from the stack (ndo_set_rx_mode)
should allow manual steering but not removal. Currently we have a
special case for Siena's all-multicast and all-unicast MAC filters,
but on EF10 we need to allow for steering of precise MAC filters as
well.
The EFX_FILTER_FLAG_RX_STACK flag changes the behaviour of replacement
and removal requests:
- Replacement *of* a filter with this flag never clears the flag but
does change steering and saved priority
- Replacement *by* a filter with this flag only sets the flag but does
not change steering
- Removal with priority < EFX_FILTER_PRI_REQUIRED really resets RX
steering and saved priority
This could support precise MAC filtering on Siena in future.
As a side-benefit, the default MAC filters are hidden from ethtool
until they are steered.

Replace type field with match_flags. Add rss_context and match values
covering of most of what is now in the MCDI protocol.
Change some fields into bitfields so that the structure size doesn't grow
beyond 64 bytes.
Ditch the filter decoding functions as it is now easier to pick apart
the abstract structure.
Rewrite ethtool NFC rule functions to set/get filter match flags and
values directly.

This filter flag cannot yet be set through the ethtool command and
will not be supported on future hardware.

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.

Also add note that the efx_filter_spec::priority field has nothing
to do with priority between multiple matching filters.

Moves the Solarflare drivers into drivers/net/ethernet/sfc/ and
make the necessary Kconfig and Makefile changes.
