Description (partial)

Symptom:
- Server will not complete discovery
- stuck at FSM 0% fetching adapter and get an error message: lBits is 0#lBits is 0#ERROR: Error adding TLV

- The portAG logs show "error getting chassis inventory, details: ERROR: Error adding TLV"
- The rsdAG logs show the server appears to properly get DHCP address from UCSM, but doesn't seem to get further in discovery


- Per the logs, we are failing to set a specific attribute when we execute the following command:

[INFO][0x73a2eb90][Feb 12 18:53:12.497][app_sam_portAG:SC_Send] Executing command: (TLVs) cmd: 294, argc: 0; show interface chassis-info <<<<<<<
