[systemd-devel] Proposal: Add biosdevname naming scheme to systemd

[Jordan Hargrave]

There are currently two competing naming mechanisms for network cards,
biosdevname and systemd.  Systemd currently has some limitations on naming
cards that use network partitioning or support SR-IOV.  Proposal is to add
support for biosdevname-like names as part of systemd.  The names would be
created as a new environment variable ID_NET_NAME_BIOSDEVNAME.  This could
then be used in the udev rules scripts to replace the external biosdevname
handler.

At least on Dell systems, systemd generates unusable names (PCI B:D:F vs
Slot#) for add-in cards as our PCIe slots do not have the ACPI _SUN method,
but they do have a SMBIOS slot number.
