Updated git commit as

    eventdev/eth_rx: fix missing internal port checks

    When event delivery is through internal port, stats are mainitained
    by HW and we should avoid reading SW data structures for stats.
    Fix missing internal port checks.

    Fixes: 995b150c1ae1 ("eventdev/eth_rx: add queue stats API")
    Cc: stable@dpdk.org
