Online address changes
CA or DB puts to a link field will change its destination.
- The new link address string is parsed and checked.
- The old lset->delete() routine is called and its link value memory returned to the OS.
- The new LSET address is found, and memory allocated for the new link value.
- Parsed address arguments are copied into the new link value struct.
- The new lset->add() routine is called.
The existing device support interface cannot completely implement soft channel support through this API, for which it must call the lset->delete() and lset->add routines when the link changes.
