Implemented get session info cmd in host interface
This command can get info of any session Tested all positive and negative test cases Tested: Get active session info by valid session handle ipmitool raw 0x6 0x3d <sesssion index = search session by handle> <valid session handle> Response : successfully gets the session info as per IPMI spec Get active session info by valid session id ipmitool raw 0x6 0x3d <sesssion index = search session by id> <valid session id> Response : successfully gets the session info as per IPMI spec Get inactive session info by valid session handle ipmitool raw 0x6 0x3d <sesssion index = search session by handle> <valid session handle> Response : successfully gets the session info as per IPMI spec Get inactive session info by valid session id ipmitool raw 0x6 0x3d <sesssion index = search session by id> <valid session id> Response : successfully gets the session info as per IPMI spec Get session info by invalid session handle ipmitool raw 0x6 0x3d <sesssion index = search session by handle> <invalid session handle> Response : 0x88 // Inavlid Session Handle Get session info by invalid session id ipmitool raw 0x6 0x3d <sesssion index = search session by id> <invalid session id> Response : 0x87 // Inavlid Session Id Signed-off-by: Rajashekar Gade Reddy <raja.sekhar.reddy.gade@linux.intel.com> Change-Id: Ib36a9fe5eac58d15011cc9379ceed480ba0be96d
