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.
