VLAN interface creation will be handled by exec commands in topology
since ifupdown-ng can't reliably create VLAN sub-interfaces on bonds.
Removed 'inet manual' to allow bond0 to come up automatically.
The bonding executor must be explicitly enabled with 'use bond'
for ifupdown-ng to create the bond interface properly.
Requires 'bonding' package installed.
Tested and verified working:
- bond0 created with LACP (802.3ad) mode
- eth1 and eth2 enslaved to bond0
- VLAN interface bond0.40 working
- MLAG showing active-full on switches
