src/sys/net/if_me.c:522]: (style) Suspicious condition (assignment + comparison); Clarify expression with parentheses.

Source code is

       if (sc == NULL || !ME_READY(sc) ||
            (ifp->if_flags & IFF_MONITOR) != 0 ||
            (ifp->if_flags & IFF_UP) == 0 ||
            (error = me_check_nesting(ifp, m) != 0)) {

maybe better code

       if (sc == NULL || !ME_READY(sc) ||
            (ifp->if_flags & IFF_MONITOR) != 0 ||
            (ifp->if_flags & IFF_UP) == 0 ||
            (error = me_check_nesting(ifp, m)) != 0) {
