This series adds features in NPC HW block in the OcteonTX2 AF driver
for better observability, configuration, and resource management.

Patch 1 adds debugfs enhancements for CN20K: mcam_layout now shows
enabled/disabled state per MCAM entry; a new "dstats" entry reports hit
counts with delta semantics; and "mismatch" lists entries that are
enabled but not explicitly allocated.

Patch 2 (from Saeed) extends devlink with DEVLINK_PARAM_TYPE_U32_ARRAY
so params can accept multiple u32 values in a single value. This is
used by patch 3 for subbank search order.

Patch 3 adds a devlink parameter "srch_order" for CN20K to control
the order in which NPC subbanks are searched during MCAM allocation,
allowing users to tune rule priority without firmware changes.

Patch 4 ties default MCAM entries (broadcast, multicast, promisc, ucast)
to NIX LF lifetime: they are allocated when a NIX LF is allocated and
freed when it is released, improving MCAM utilization.
NIX_LF_DONT_FREE_DFT_IDXS lets the kernel PF retain default entries
across suspend/resume.

Patch 5 allows loading a custom KPU profile from the filesystem via
a module parameter (kpu_profile=), avoiding firmware flashes for
profile updates.
