IB/ehca: HW level, HW caps and MTU autodetection
In preparation for support of new eHCA2 features, change adapter probing: - Hardware level is changed to encode major and minor chip version - Hardware capabilities are queried from the firmware - The maximum MTU is queried from the firmware instead of assuming a fixed value Signed-off-by: Joachim Fenkes <fenkes@de.ibm.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
