INITIALIZATION

TEST PROCEDURE

If HAVE_HOMELINK is true in config.txt
Check Link0 routing table 
  NUT
(Link0)   MN0X    MN0Y
   |       |       |
   | <---- |       | Echo Request
   | ----> |       | Echo Reply (*1)
   |       |       |
   | <------------ | Echo Request
   | ------------> | Echo Reply (*2)
   |       |       |


1. MN0X sends Echo Request
2. MN0X receives Echo Reply (*1)
3. MN0Y sends Echo Request
4. MN0Y receives Echo Reply (*2)
If HAVE_FOREIGN is true in config.txt
Check Link1 routing table 
  NUT
(Link0)   MN1X    MN1Y
   |       |       |
   | <---- |       | Echo Request
   | ----> |       | Echo Reply (*3)
   |       |       |
   | <------------ | Echo Request
   | ------------> | Echo Reply (*4)
   |       |       |


5. MN1X sends Echo Request
6. MN1X receives Echo Reply (*3)
7. MN1Y sends Echo Request
8. MN1Y receives Echo Reply (*4)
