biosdevname hitting rawhide

I've just pushed biosdevname-0.3.1 into rawhide. This is not yet
installed by default as part of @base, nor is it used by anaconda, but
those changes will come over the next few days.
biosdevname, on at least Dell 10G and newer, and HP 6G and newer
servers, provides "better" BIOS-suggested names for embedded NIC
ports, and NIC ports on add-in PCI cards. If you have existing names,
as defined in /etc/udev/rules.d/70-persistent-net.rules, those names
will continue to be used, and biosdevname won't ever be invoked.
Likewise, if you have device names assigned to MAC addresses in
/etc/sysconfig/network-scripts/ifcfg-eth*, biosdevname won't be
invoked. But going forward, on new installs, biosdevname _will_ be
used to change the names.
The naming scheme is thus:
Embedded ports: em<port>
PCI cards: pci<slot>#<port>_<virtual function> (the latter on SR-IOV
and soon Network Partitioned (NPAR) devices).
If you have a Dell or HP server, and would like to try it out, please:
# yum install biosdevname
# rm /etc/udev/rules.d/70-persistent-net.rules
# sed -i -e '/^HWADDR=/d' /etc/sysconfig/network-scripts/ifcfg-eth*
# rmmod <your ethernet drivers>
# modprobe <your ethernet drivers>
(or reboot instead)
# ifconfig -a
will show all the devices with the new naming scheme.
