[pve-devel] [PATCH pve-manager v5 1/2] lxc: show dynamically assigned IPs in network tab

[Gabriel Goller <g.goller@proxmox.com>]

Adds a call to /nodes/{node}/lxc/{vmid}/interfaces and merges the
returned data with the existing configuration. This will update the
IPv4 and IPv6 address, as well as the interface name (in case the
container changed it).
