[pve-devel] [PATCH pve-common v3 2/2] iproute2: add helper for querying vlan information

[Stefan Hanreich <s.hanreich@proxmox.com>]

'-compressvlans' is used by default, because PVE configures VLAN
1-4094 by default on all ports on a VLAN-aware bridge and having one
entry per VLAN in this case is quite excessive.
