The array ib_mad_mgmt_class_table.method_table has MAX_MGMT_CLASS (80) elements. Hence compare the array index with that value instead of with IB_MGMT_MAX_METHODS (128). This patch avoids that Coverity reports the following: Overrunning array class->method_table of 80 8-byte elements at element index 127 (byte offset 1016) using index convert_mgmt_class(mad_hdr->mgmt_class) (which evaluates to 127).
