The Azure MANA folks would like the PCI domain to be suppressed from naming network interfaces. Let's introduce a somewhat generic way to do this, without hardcoding anything to Azure. Specifically: we'll ship a new hwdb entry that sets a new ID_NET_NAME_INCLUDE_DOMAIN=0 property on relevant MANA devices. Then we make net_id look for that property, and if it is set we simply suppress the PCI domain. (Untested as of now, needs feedback from Azure MANA folks that this actually works and does what is requested here).
Files in this directory specify a description of hardware devices, in the form of mappings from modalias-like keys (which identify specific hardware devices) to udev properties. Files in this directory are not read by udev directly. Instead, man:systemd-hwdb(8) compiles them into a binary database. See man:hwdb(7) for an overview of the configuration file format, and man:systemd-udevd.service(8) for a description of the udev daemon. Use 'systemd-analyze cat-config udev/hwdb.d' to display the effective config.
