Use flow_rule_is_supp_control_flags() to reject filters with
unsupported control flags.
In case any unsupported control flags are masked,
flow_rule_is_supp_control_flags() sets a NL extended
error message, and we return -EOPNOTSUPP.
Only compile-tested.

As 32bits of dissector->used_keys are exhausted,
increase the size to 64bits.
This is base change for ESP/AH flow dissector patch.

Enable the TC command to use the lan966x ES0 VCAP. Currently support
only one action which is vlan pop, other will be added later.

IS1 VCAP has it's own list of supported ethernet protocol types which is
different than the IS2 VCAP. Therefore separate the list of known
protocol types based on the VCAP type.

Allow rules to be chained between IS1 VCAP and IS2 VCAP. Chaining
between IS1 lookups or between IS2 lookups are not supported by the

Since commit 81e164c4aec5 ("net: microchip: sparx5: Add automatic
selection of VCAP rule actionset") the VCAP API has the capability to
select automatically the actionset based on the actions that are attached
to the rule. So it is not needed anymore to hardcode the actionset in the
driver, therefore it is OK to remove this.

Add the following TC flower filter keys to lan966x for IS2:
- ipv4_addr (sip and dip)
- ipv6_addr (sip and dip)
- control (IPv4 fragments)
- portnum (tcp and udp port numbers)
- basic (L3 and L4 protocol)
- vlan (outer vlan tag info)
- tcp (tcp flags)
- ip (tos field)
As the parsing of these keys is similar between lan966x and sparx5, move
the code in a separate file to be shared by these 2 chips. And put the
specific parsing outside of the common functions.

This allows the check of the goto action to be specific to the ingress and
egress VCAP instances.
The debugfs support is also updated to show this information.

This changes the way the chain information verified when adding a new tc
flower filter.
When adding a flower filter it is now checked that the filter contains a
goto action to one of the IS2 VCAP lookups, except for the last lookup
which may omit this goto action.
It is also checked if you attempt to add multiple matchall filters to
enable the same VCAP lookup. This will be rejected.

Currently lan966x, doesn't allow to run PTP over interfaces that are
part of the bridge. The reason is when the lan966x was receiving a
PTP frame (regardless if L2/IPv4/IPv6) the HW it would flood this
frame.
Now that it is possible to add VCAP rules to the HW, such to trap these
frames to the CPU, it is possible to run PTP also over interfaces that
are part of the bridge.
