[Bad commit]

commit a9b0d056440cd0f52de752e49e45e2d3255c5aca

    net/bnxt: fix xstats names query overrun

    [ upstream commit 8dcee14fbfca8c90cd09c88e0fda65819d82ded6 ]

    When the xstats_names parameter to rte_eth_xstats_get_names()
    is non-NULL and the size parameter is less than the required
    number of entries, the driver must return the required size
    without modifying (and over-running) the caller's xstats_names
    array.

    Update bnxt_dev_xstats_get_names_op() in accordance with this
    requirement.

    Fixes: bfb9c2260be2 ("net/bnxt: support xstats get/reset")
