[pve-devel] [PATCH common/manager/network 0/3] bookworm: fix VLAN handling on vlan-unaware bridges with pinned NIC names

There were mainly two issues related to this:
* generating SDN configuration for VLAN and QinQ zones that use vlan-unaware
  bridges
* tagging network devices of VMs on vlan-unaware bridges

In both cases the detection of the underlying physical ports relied on a regex,
that doesn't work with pinned names at all. Switch over to using `ip link` for
the detection of physical ports, since network interfaces can now have names
that do not need to have a specific prefix at all. For SDN, we add a new change
detection mechanism to `pve-sdn-commit`, that reloads the SDN configuration if
there is a vlan-unaware bridge used as the underlying bridge of a VLAN / QinQ
zone. This ensures that the network configuration gets regenerated properly
if pinning takes place, after a VLAN or QinQ zone have been created.

Since bookworm doesn't have the IPRoute2 helper yet, it has one commit less than
the trixie one, because the helper is added directly to pve-sdn-commit.
