Haven't seen an ERI in the wild yet, and haven't Googled it, so don't know that 
one.

The *BSD's also do this sort of thing.

I would love something more consistent, similar to the cisco naming (even 
though depending upon which BU the device is from, interfaces and slots can 
either start with 0 or start with 1, but that's a digression).  

But PC hardware is so much more variable than cisco stuff is, and motherboards 
can have different lanes (for PCI-e) out of order relative to the slots, and 
server motherboards especially (like a SuperMicro P4DP6 to pull one off the top 
of my head) have multiple buses, so that the fifth slot is actually something 
like the third bus's second slot or similar, meaning you have to dig out the 
manual, and that's often of no help at all.  Need the ability to 'blink LEDs' 
at times other than installation, IMO. (yes, you have this already in Fedora; 
install ethtool, and use ethtool -p $devname )

The current 'ethX' convention breaks in odd ways for different use cases. 
Especially when you replace a lightning-toasted NIC.

And I have personally seen PCI enumeration order change on seemingly a whim, 
both due to kernel updates (this was EL4, so not a kernel version upgrade) and 
due to BIOS updates.  And I'm not just talking slot order on a bus, but bus 
order on the northbridge.  (Serverworks chipset in one instance, Intel chipset 
in another.)

The fact of the matter is that consistent PC device enumeration is a hard 
problem, and people are working towards making this more consistent and better 
from the end-users' points of view. And I appreciate the effort, even with the 
bugs.

Windows has the same problem, just a different flavor, and I've hit that, too, 
with XP, Vista, Server 2003, 7, and Server 2008.
