purpose of slaveIndex metal network configuration option

[vitush93]

Hi, looking at docs, I'm wondering whats the purpose of slaveIndex option and how different configurations behave in practice:

• default for all links is 0 and seems to be working just fine
• difference between defaults (0) and incremental indexes as per documentation?
• given 4 links, what would using 0, 0 and 1, 1 mean?

example:

links:
    - name: eth0
      up: true
      masterName: bond0
      slaveIndex: 0
      layer: platform
    - name: eth1
      up: true
      masterName: bond0
      slaveIndex: 0
      layer: platform
    - name: eth2
      up: true
      masterName: bond0
      slaveIndex: 1
      layer: platform
    - name: eth3
      up: true
      masterName: bond0
      slaveIndex: 1
      layer: platform

thank for helping me understand.

They should increment in the order of the links bonded, e.g. 0, 1, 2, 3. It depends on bond type, but most of them are critical to put links in the correct order.

right, so this matters for other bond modes 👍

this is for LACP so I guess it's ignored then
