3aaff32304 mlxsw: spectrum_acl: Implement TC block sharing
Benefit from the prepared TC and in-driver ACL infrastructure and
introduce block sharing offload. For that, a new struct "block" is
introduced in spectrum_acl in order to hold a list of specific
block-port bindings.

In order to prepare for follow-up changes, make the bind/unbind helpers
very simple. That required move of ht insertion/removal and bind/unbind
calls into mlxsw_sp_acl_ruleset_create/destroy.

9cb3fa940e mlxsw: acl: Change trap ACL action to get the trap_id as a parameter
Allow the trap ACL action to be configured with different traps. This
allows the multicast router offloading code to use that same ACL action
with the multicast router traps. By using different traps, the multicast
router can have different trap policies and can handle the packet
differently.

d3b939b8f9 mlxsw: spectrum: Move ACL flexible actions instance to spectrum
A flexible action instance allows, given a set of ops, creating, committing
and sharing a set of ACL action blocks. The flexible action instance in
question is using the spectrum KVD linear space to store the flexible
action sets.

Move this flexible action instance to the common spectrum struct to allow
other users (such as multicast router) to get that functionality.

Reflect chain index coming down from TC core and create a ruleset per
chain. Note that only chain 0, being the implicit chain, is bound to the

a110748725 mlxsw: spectrum: Implement common FID core
The device supports three types of FIDs. 802.1Q and 802.1D FIDs for
VLAN-aware and VLAN-unaware bridges (respectively) and rFIDs to
transport packets to the router block.

The different users (e.g., bridge, router, ACLs) of the FIDs
infrastructure need not know about the internal FIDs implementation and
can therefore interact with it using a restricted set of exported
functions.

By encapsulating the entire FID logic and hiding it from the rest of the
driver we get a code base that it much simpler and easier to work with
and extend.

For example, in the current Spectrum ASIC only 802.1D FIDs can be
assigned a VNI, but future ASICs will also support 802.1Q FIDs. With
this patch in place, support for future ASICs can be easily added by
implementing a new FID operations according to their capabilities.

22a677661f mlxsw: spectrum: Introduce ACL core with simple TCAM implementation
Add ACL core infrastructure for Spectrum ASIC. This infra provides an
abstraction layer over specific HW implementations. There are two basic
objects used. One is "rule" and the second is "ruleset" which serves as a
container of multiple rules. In general, within one ruleset the rules are
allowed to have multiple priorities and masks. Each ruleset is bound to
either ingress or egress a of port netdevice.

The initial TCAM implementation is very simple and limited. It utilizes
parman lsort manager to take care of TCAM region layout.
