However, the firmware also reports a limit on the maximum descriptor size allowed, and because mthca takes into account the worst case send request overhead when checking whether to allow a QP to be created, the largest number of scatter/gather entries that can be used with mthca may be limited by the maximum descriptor size rather than just by the actual s/g entry limit. This means that applications cannot actually create QPs with max_send_sge equal to the limit returned by ib_query_device(). Fix this by checking if the maximum descriptor size imposes a lower limit and if so returning that lower limit.
