Performing string append operations when using a ``StringBuilder`` defeats
purpose of the class. Please change to the following to avoid unnecessary
string re-allocation:
```
fsBuilder.append(" <interface mac='")
.append(address.getKey() )
.append("' vsp-vr-ip='")
.append(address.getValue())
.append("'></interface>\n");
```
