            Bug ID: 2044
           Summary: mempool/cnxk: halo_ena stored one byte, caller
                    supplies four
           Product: DPDK
           Version: 26.11
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: minor
          Priority: Normal
         Component: ethdev
          Assignee: dev@dpdk.org
          Reporter: stephen@networkplumber.org
  Target Milestone: ---

drivers/mempool/cnxk/cnxk_mempool.c

parse_halo_ena_handler() stores a uint8_t:

        *(uint8_t *)extra_args = val;

while the caller declares:

        uint32_t halo_ena = 0;

Only correct because the local is pre-zeroed and the host is little
endian. The mildest of the set -- no overrun, just an incomplete store.

Fixes: 45abbfc836b1 ("mempool/cnxk: support HALO in mempool")
