Slave interfaces fall out from bonding during configuration change
Closed, ResolvedPublicBUG
Actions

Description

If we change the configuration for a slave interface, it falls out from a bonding.
How to reproduce:

set interfaces bonding bond0 member interface 'eth1'
set interfaces bonding bond0 member interface 'eth2'
commit
ip -d l
cat /proc/net/bonding/bond0

set interfaces ethernet eth2 description 'TEST'
commit
ip -d l
cat /proc/net/bonding/bond0

For some reason is_bond_member is not in the configuration after the description
eth2 with option is_bond_member
eth3 without option is_bond_member

zsdc mentioned this in T4361: `vyos.config.exists()` does not work for nodes with multiple values.Apr 14 2022, 5:39 PM

The issue with this check
A possible original issue with the function exists as it checks the only first value

bond
  member
    - eth2
    - eth3

It returns only eth2 as a member of the bonding
