In the following case, The second command( fru edit 0 field b 2 SA0531) breaks fru data, causing fru print cannot display correctly.

1） ipmitool -I lanplus -H 100.2.76.176 -U admin -P admin fru print 0 //in this case, fru only have Board domain.
Board Mfg Date : Wed Dec 2 15:20:00 2020
Board Mfg : Inspur
Board Product : Riser
Board Serial : 0
Board Part Number : YZRI-01647-101

2） ipmitool -I lanplus -H XXXX -U xxx -P xxx fru edit 0 field b 2 SA0531
String size are not equal, resizing fru to fit new string
Read All FRU area
Fru Size : 256 bytes
Copy to new FRU
Section Length: 40
Padding Length: 0
NumByte Change: 4
Start SecChnge: c2
End SecChnge : 49
Start Section : 1
End Sec wo Pad: c1
End Section : 2a
New Padding Length: -4
change_size_by_8: 1
New Padding Length: 4
change_size_by_8: 1
header.offset.board: 1
Moving Section Product, from 0 to 8
Change multi offset from 0 to 1
Moving Remaining Bytes (Multi-Rec , etc..), from 0 to 8
Updating Field : '0 ' with 'SA0531' ... (Length from '194' to '198')
Copying remaining of sections: 21
Calculate New Checksum: ffffffca
Writing new FRU.
Done.

3） ipmitool -I lanplus -H 100.2.76.176 -U admin -P admin fru print 0 //nothing can display

4)The reason is that only board domain is not considered in frutool, and the solution can refer to the pull request code.
