As the configuration for the Sparx5 IS2 VCAP consists of one (or more)
keyset(s) for each lookup/port per traffic classification, it is not
always possible to cover all protocols with just one ordinary VCAP rule.
To improve this situation the driver will try to find out what keysets a
rule will need to cover a TC flower "protocol all" filter and then compare
this set of keysets to what the hardware is currently configured for.
In case multiple keysets are needed then the driver can create a rule per
rule size (e.g. X6 and X12) and use a mask on the keyset type field to
allow the VCAP to match more than one keyset with just one rule.
This is possible because the keysets that have the same size typically has
many keys in common, so the VCAP rule keys can make a common match.
The result is that one TC filter command may create multiple IS2 VCAP rules
of different sizes that have a type field with a masked type id.
Delivery:
=========
This is current plan for delivering the full VCAP feature set of Sparx5:
- Sparx5 IS0 VCAP support
- TC policer and drop action support (depends on the Sparx5 QoS support
upstreamed separately)
- Sparx5 ES0 VCAP support
- TC flower template support
- TC matchall filter support for mirroring and policing ports
- TC flower filter mirror action support
- Sparx5 ES2 VCAP support

v2 Fixed a NULL return value compiler warning.

The VCAP API exposes a /sys/kernel/debug/sparx5/vcaps folder containing
the following entries:
- raw_<vcap>_<instance>
This is a raw dump of the VCAP instance with a line for each available
VCAP rule. This information is limited to the VCAP rule address, the
rule size and the rule keyset name as this requires very little
information from the VCAP cache.
This can be used to detect if a valid rule is stored at the correct
address.
- <vcap>_<instance>
This dumps the VCAP instance configuration: address ranges, chain id
ranges, word size of keys and actions etc, and for each VCAP rule the
details of keys (values and masks) and actions are shown.
This is useful when discovering if the expected rule is present and in
which order it will be matched.
- <interface>
This shows the keyset configuration per lookup and traffic type and the
set of sticky bits (common for all interfaces). This is cleared when
shown, so it is possible to sample over a period of time.
It also shows if this port/lookup is enabled for matching in the VCAP.
This can be used to find out which keyset the traffic being sent to a
port, will be matched against, and if such traffic has been seen by one
of the ports.
Delivery:
=========
This is current plan for delivering the full VCAP feature set of Sparx5:
- TC protocol all support for IS2 VCAP
- Sparx5 IS0 VCAP support
- TC policer and drop action support (depends on the Sparx5 QoS support
upstreamed separately)
- Sparx5 ES0 VCAP support
- TC flower template support
- TC matchall filter support for mirroring and policing ports
- TC flower filter mirror action support
- Sparx5 ES2 VCAP support
Version History:
================
v2 Removed a 'support' folder (used for integration testing) that had
been added in patch 6/8 by a mistake.
Wrapped long lines.

The actionset is not decoded in full as the Sparx5 IS2 only has one

Andy Chiu says:
====================
net: axienet: Use a DT property to configure frequency of the MDIO bus
Some FPGA platforms have to set frequency of the MDIO bus lower than 2.5
MHz. Thus, we use a DT property, which is "clock-frequency", to work
with it at boot time. The default 2.5 MHz would be set if the property
is not pressent. Also, factor out mdio enable/disable functions due to
the api change since 253761a0e61b7.
Changelog:
--- v5 ---
1. Make dt-binding patch prior to the implementation patch.
2. Disable mdio bus in error path.
3. Update description of some functions.
--- v4 ---
1. change MAX_MDIO_FREQ to DEFAULT_MDIO_FREQ as suggested by Andrew.
--- v3 RESEND ---
1. Repost the exact same patch again
--- v3 ---
1. Fix coding style, and make probing of the driver fail if MDC overflow
--- v2 ---
1. Use clock-frequency, as defined in mdio.yaml, to configure MDIO
clock.
2. Only print out frequency if it is set to a non-standard value.
3. Reduce the scope of axienet_mdio_enable and remove
axienet_mdio_disable because no one really uses it anymore.

bna: Avoid clashing function prototypes
When built with Control Flow Integrity, function prototypes between
caller and function declaration must match. These mismatches are visible
at compile time with the new -Wcast-function-type-strict in Clang[1].
Fix a total of 227 warnings like these:
drivers/net/ethernet/brocade/bna/bna_enet.c:519:3: warning: cast from 'void (*)(struct bna_ethport *, enum bna_ethport_event)' to 'bfa_fsm_t' (aka 'void (*)(void *, int)') converts to incompatible function type [-Wcast-function-type-strict]

The bna state machine code heavily overloads its state machine functions,
so these have been separated into their own sets of structs, enums,
typedefs, and helper functions. There are almost zero binary code changes,
all seem to be related to header file line numbers changing, or the
addition of the new stats helper.
