From: Rao Shoaib <rshoaib@xxxxxxxxxxxxxxxxxxxxxxx>
In our internal testing we have found that the
current maximum are too smalls. Ideally there should
be no limits but currently maximum values are reported
via ibv_query_device, so we have to keep maximum values
but they have been made suffiently large.
Resubmitting after fixing an issue reported by test robot.
