2022-10-24net: microchip: sparx5: Adding basic rule management in VCAP APISteen Hegelund
This provides most of the rule handling needed to add a new rule to a VCAP. To add a rule a client must follow these steps: 1) Allocate a new rule (provide an id or get one automatically assigned) 2) Add keys to the rule 3) Add actions to the rule 4) Optionally set a keyset on the rule 5) Optionally set an actionset on the rule 6) Validate the rule (this will add keyset and actionset if not specified in the previous steps) 7) Add the rule (if the validation was successful) 8) Free the rule instance (a copy has been added to the VCAP) The validation step will fail if there are no keysets with the requested keys, or there are no actionsets with the requested actions. The validation will also fail if the keyset is not configured for the port for the requested protocol).

2022-10-24net: microchip: sparx5: Adding port keyset config and callback interfaceSteen Hegelund
This provides a default port keyset configuration for the Sparx5 IS2 VCAP where all ports and all lookups in IS2 use the same keyset (MAC_ETYPE) for all types of traffic. This means that no matter what frame type is received on any front port it will generate the MAC_ETYPE keyset in the IS VCAP and any rule in the IS2 VCAP that uses this keyset will be matched against the keys in the MAC_ETYPE keyset. The callback interface used by the VCAP API is populated with Sparx5 specific handler functions that takes care of the actual reading and writing to data to the Sparx5 IS2 VCAP instance. A few functions are also added to the VCAP API to support addition of rule fields such as the ingress port mask and the lookup bit. The IS2 VCAP in Sparx5 is really divided in two instances with lookup 0 and 1 in the first instance and lookup 2 and 3 in the second instance. The lookup bit selects lookup 0 or 3 in the respective instance when it is set.

2022-10-24net: microchip: sparx5: Adding initial tc flower support for VCAP APISteen Hegelund
This adds initial TC flower filter support to Sparx5 for the IS2 VCAP. The support consists of the source and destination MAC addresses, and the trap and pass actions.

2022-02-17net: sparx5: remove guards against !BRIDGE_VLAN_INFO_BRENTRYVladimir Oltean
Since commit 3116ad0696dd ("net: bridge: vlan: don't notify to switchdev master VLANs without BRENTRY flag"), the bridge no longer emits switchdev notifiers for VLANs that don't have the BRIDGE_VLAN_INFO_BRENTRY flag, so these checks are dead code. Remove them. Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Phylink will use PCS polling whenever phylink_config.pcs_poll or the phylink_pcs poll member is set. As this driver sets both, remove the former. Signed-off-by: Russell King (Oracle) <rmk+kernel@armlinux.org.uk> Signed-off-by: David S. Miller <davem@davemloft.net>
2022-02-03net: sparx5: Fix get_stat64 crash in tcpdumpSteen Hegelund
This problem was found with Sparx5 when the tcpdump tool requests the do_get_stats64 (sparx5_get_stats64) statistic. The portstats pointer was incorrectly incremented when fetching priority based statistics.
