For #5 - you can check opensm version included with MLNX OFED by typing "opensm --version". For example on MLNX OFED 2.3-1.0.1 you will get "OpenSM 4.2.5.MLNX20140828.7f05469"
On switches SM version is reported under "IB SM Mgmt" menu. For example MLNX OS ver. 3.3.3500 reports "OpenSM3.3.13.MLNX_20121224_9b362db"
and MLNX OS ver. 3.4.0000 reports

you can change back the mtu to 2K from 4K with using the below command for each physical port:
echo "2048" > /sys/class/net/ib0/device/mlx4_port1_mtu
Thank you for all of your reply.
Thank you so much!
