Subject: How to display IPv4 array?
Date: Tue, 12 Mar 2024 18:08:33 +0800	[thread overview]
Message-ID: <ZfApoTpVaiaoH1F0@Laptop-X1> (raw)

Hi Jakub,

I plan to add bond support for Documentation/netlink/specs/rt_link.yaml. While
dealing with the attrs. I got a problem about how to show the bonding arp/ns
targets. Because the arp/ns targets are filled as an array[1]. I tried
something like:

  -
    name: linkinfo-bond-attrs
    name-prefix: ifla-bond-
    attributes:
      -
        name: arp-ip-target
        type: nest
        nested-attributes: ipv4-addr
  -
    name: ipv4-addr
    attributes:
      -
        name: addr
        type: binary
        display-hint: ipv4

But this failed with error: Exception: Space 'ipv4-addr' has no attribute with value '0'
Do you have any suggestion?

Thanks
