 On BMC version 1.43.660a4315, security revision is upgraded.
Q1: Why I can't downgrade to previous BMC version.
A1: Downgrading below 1.43.660a4315 is not supported due to a security revision change.

 On BMC version 1.90.0cf6e935, default cipher suite was chaged from version 3 to version 17.
Q2: Why I can't connect with IPMI through LAN to BMC from version 1.90.0cf6e935.
A2: Extra parameters for ipmitool through LAN is required since BMC firmware 1.90.0cf6e935, 
     the “-C 17” is a must when using ipmitool to access BMC LAN.
