    Some questions about mlx_core and mlx_ib parameter.

      Hello All,


      Customer want to upgrade their OFED driver version from v.1.5.3-4.0.44 to v2.2-1.0.1.

      Before apply for new OFED in production system, They want to check some of changed default parameter value and others in v2.2-1.0.1 comparing to v1.5.3-4.0.44.


      1). regarding "internal_err_reset" mlx4_core parameter, default value was changed from enable to disable in v2.2-1.0.1, what is exactly meaning of this parameter and which case do customer need to change default value to enable again in v2.2-1.0.0?


      2). In case of "set_4K_assign" parameter, It automatically set MTU size as a 4K without any setting in v2.2-1.0.0, Is there any way to change the value to 2K or others?


      3). In case of "sm_guide_assign" parameter in mlx4_ib, It have default value as "1", How can we use GUID alias?


      4). what is a meaning of changing default value form 2- >0 in "max_rqw_ethy_qp" and none -> 427 in "hca_core_clock" parameter out put with ibv_devinfo ?


      5). How can I check the OpenSM version in version of OFED v2.3-1.0.0, MLNX OS v3.3.4402 and MLNX OS v.3.3.5506?


      It will be very happy to hear any reply and answer about this question.


      Thanks in advance!
