[Bad commit]

commit 339f1ba5135367e566c3ca9db68910fd8c7a6448 (HEAD, refs/bisect/bad)

    net/bonding: make configure method re-entrant

    According to the documentation, rte_eth_dev_configure()
    can be invoked repeatedly while in stopped state.
    The current implementation in the bonding driver
    allows for that (technically), but the user sees
    warnings which say that back-end devices have
    already been harnessed. Re-factor the code
    to have cleanup before each (re-)configure.
