[Why] Nodes need to communicate with each other when testing cluster jobs. Ips can bind to on macs after setting 'direct_mac' and 'direct_ips' for cluster jobs

[HowTo]

1. Need a cluster config file in $LKP_SRC/cluster,

for example:

assumption: <assumption01>
switch: switch01
ip0: 3

---

vm-2p8g--renwen:
  roles: [ server ]
  macs: [ "ec:f4:bb:cb:7b:92" ]

vm-2p4g--renwen:
  roles: [ client ]
  macs: [ "ec:f4:bb:cb:54:90" ]

nr_node=2 cs1 switch=sw1 ip0=0 ($ip_prefix.0-.1) cs2 switch=sw1 ip0=2 ($ip_prefix.2-.3)

This means cs1 or cs2 both have ip0, and this ip0 means the physical machine's last mask scope? if switch same they are use same ip_prefix.

...

"switch": only need if 2+ clusters share the same switch "ip0": only need if shared switch, and != 0

The ip0 field is mandatory not only if shared switch, it's the cluster machine's ip scope.

...

"assumption": the info about this cluster config

How to write this "assumption"? may be can give a exaple.

...

2. Scheduler get config from config file and set 'direct_macs' and

'direct_ips' for jobs.

3. When running a cluster job, bind direct_ips to direct_ macs

in test environment.

4. Test client connect with daemon client to test job.
