[PATCH proxmox-datacenter-manager] fix #7187: report: add ethtool output for physical interfaces

[Erik Fastermann <e.fastermann@proxmox.com>]

The implementation mirrors the change in proxmox-backup,
as the report functionality in pdm is adapted from there.

Signed-off-by: Erik Fastermann <e.fastermann@proxmox.com>

 NOTE: A similar patch was applied to all products:
 pmg, pve, pbs, pdm.
