CHANGES WITH 239 in spe:
* NETWORK INTERFACE DEVICE NAMING CHANGES: elogind-udevd's "net_id"
- builtin may name network interfaces differently than in previous
- versions. SR-IOV virtual functions and NPAR partitions with PCI
- function numbers of 8 and above will be named more predictably, and
- udev may generate names based on the PCI slot number in some cases
- where it previously did not.
+ builtin will name network interfaces differently than in previous
+ versions for virtual network interfaces created with SR-IOV and NPAR
+ and for devices where the PCI network controller device does not have
+ a slot number associated.
+
+ SR-IOV virtual devices are now named based on the name of the parent
+ interface, with a suffix of "v<N>", where <N> is the virtual device
+ number. Previously those virtual devices were named as if completely
+ independent.
+
+ The ninth and later NPAR virtual devices will be named following the
+ scheme used for the first eight NPAR partitions. Previously those
+ devices were not renamed and the kernel default (eth<n>) was used.
+
+ "net_id" will also generate names for PCI devices where the PCI
+ network controller device does not have an associated slot number
+ itself, but one of its parents does. Previously those devices were
+ not renamed and the kernel default (eth<n>) was used.
* AF_INET and AF_INET6 are dropped from RestrictAddressFamilies= in
elogind.service. Since v235, IPAddressDeny=any has been set to
