  Changed paths:
    M lib/ofp-util.c

  Log Message:
  ofp-util: Fix buffer overread in ofputil_pull_queue_get_config_reply10().

msg->size isn't the relevant measurement here because we're only supposed
to read 'len' bytes.  Reading more than that causes 'len' to underflow to a
large number at the end of the loop.
