mlxsw: spectrum: Allow fetch-and-clear of flow counters For the report_delta-like interface like a previous patch has added for collection of NH group statistics, it's easiest to read the counter and have the HW clear it right away. Thus, change mlxsw_sp_flow_counter_get() to take a bool indicating whether this should be done.

mlxsw: Fix some IS_ERR() vs NULL bugs The mlxsw_sp_acl_rulei_create() function is supposed to return an error pointer from mlxsw_afa_block_create(). The problem is that these functions both return NULL instead of error pointers. Half the callers expect NULL and half expect error pointers so it could lead to a NULL dereference on failure. This patch changes both of them to return error pointers and changes all the callers which checked for NULL to check for IS_ERR() instead.

So define the types in an enum and pass it down to alloc and free functions. Once the entry type is passed down, KVDL common part knows sizes of each entry types, so replace size function arg with entry count.

mlxsw: spectrum_router: Support IPv6 multicast to host CPU A step toward offloading IPv6 routing, this adds an additional multicast routing table meant for IPv6 [with its underlying TCAM region] and populates the default rule for IPv6 multicast packets. Following this, ingress IPv6 multicast packets would be trapped and delivered to the host CPU.

mlxsw: core: Make counter index allocated inside the action append So far, the caller of mlxsw_afa_block_append_counter needed to allocate counter index by hand. Benefit from the previously introduced resource infra and counter_index_get/put callbacks, and allocate the counter index in place where it is needed, inside the action append function.

mlxsw: spectrum: mr_tcam: Add trap-and-forward multicast route In addition to the current multicast route actions, which include trap route action and a forward route action, add the trap-and-forward multicast route action, and implement it in the multicast routing hardware logic. To implement that, add a trap-and-forward ACL action as the last action in the route flexible action set. The used trap is the ACL2 trap, which marks the packets with offload_mr_forward_mark, to prevent the packet from being forwarded again by the kernel. Note: At that stage the offloading logic does not support trap-and-forward multicast routes. This patch adds the support only in the hardware logic.

mlxsw: spectrum: Add the multicast routing hardware logic Implement the multicast routing hardware API introduced in previous patch for the specific spectrum hardware. The spectrum hardware multicast routes are written using the RMFT2 register and point to an ACL flexible action set. The actions used for multicast routes are: - Counter action, which allows counting bytes and packets on multicast routes. - Multicast route action, which provide RPF check and do the actual packet duplication to a list of RIFs. - Trap action, in the case the route action specified by the called is trap.
