extended netdevice naming proposal

extended netdevice naming proposal

[Matt Domsch]

While this _is_ the original bikeshedding problem, as long as I'm
going to use biosdevname to change names for embedded NICs, perhaps I
can be so bold as to change them for USB add-in cards too?

There are quite a few dimensions to the problem:
* device location (onboard, PCI, other bus)
* multiple ports on a single add-in card
* with Network Partitioning (NPAR) and SR-IOV, the OS sees multiple
  network interfaces (physical or virtual interfaces) but a single external port
* the suffix .1234 currently used for vlans (ala vconfig)
* A single PCI device may drive multiple external ports

As such, here is a naming proposal, aimed to keep within 15
characters for most configurations.

(location)(slot)#(port)/(instance).(vlan)

location := NIC on Motherboard = net1, net2, net3, net4
   (note: people hated the TLA collision with 'lom', so avoiding that here).
         := PCI slot = pci1, pci2, pci3, pci4
 these correspond to chassis labels, information is available in
 $PIRQ, SMBIOS or ACPI, which biosdevname retrieves and uses.

For single- or multi-port cards in PCI slots, append #(port):
   pci1#1, pci1#2, pci1#3, pci1#4  for 4 ports on a card in PCI slot 1

There is currently no way to get this port info from BIOS.  Several people
have suggested using adding a PCI capabilities field to expose this
info in a standard way, but that's a ways off. Until then, biosdevname
can guess (assume ascending MAC order on the single card).

For NPAR/SR-IOV where the physical port is shared by several
instances, append /(instance):
   net1/1, net1/2 pci1#1/1, pci1#1/2,
   pci1#1/2, pci1#1/3, ...

For each of the above where vconfig sets up a vlan:
   pci1#/1.1000, pci1#1/2.1001, pci1#1/2.1003, pci1#1/3.1004, ...
vconfig simply appends .{vlan#} to the already  named device when creating a new vlan netdevice.

BIOS definitely doesn't know about these, as they aren't exposed until
after the OS is running, so the mechanism that creates them (such as
following modprobe ixgbevf) would have to, and I think that can be
done with a udev rule, if we can somehow expose the port number of the
underlying PF when we throw the message to udev on creation of the VF.

And of course, BIOS knows nothing about vlans, so vconfig would add that.


If we have no more than 99 PCI slots, no more than 99 ports on a
single card, no more than 999 instances/virtual functions (we need at
least 128, perhaps more than 256 at some point, so hex vs decimal
doesn't buy us much here), no more than 4k VLANs, we get:

len("pci99#99/999.4095") = 17

If we really have that many, we're in trouble in other ways, so let's
hope that's good enough.

Thoughts?  Overkill?

Thanks,
Matt

"net", really?!  I can't say I care that much, but this just doesn't
seem like a helpful prefix.

'#' might be problematic but I don't have any concrete evidence of that.

You could try using the dev_id attribute first; it's supposed to be a
0-based index of a net device on a board.  It won't be unique in all
cases, e.g. if a NIC vendor has used a bridge chip to connect multiple
controllers on a single board or if the driver just doesn't set it.  So
you would need to fall back to MAC order in tha tcase.

Surely VFs are normally passed through to a guest, in which case:
1. The host/console/dom0 won't create a net device for them.
2. The guest won't (and shouldn't) have such information about the
physical location of the PCI function.

AIUI, the kernel explicitly rejects '/' in the name (for fairly obvious
sysfs reasons.) So you'd at least need a different delimiter. There may
also be potential confusion with pci01#03:02.0001 with someone thinking
that's bus/dev/fn, if we're being really petty.

':' is also reserved for alias interfaces, the old way of assigning
multiple IP addresses.

I would say '-' is a good separator, but that might result in ambiguity
in IRQ names.

How about underscore to separate VFs? 
(location)(slot)#(port)_(instance).(vlan)

And 'em' as prefix for embedded?

See below this implementation in biosdevname now.  This is a system
with 4 onboard NICs, plus an add-in dual-port Intel Niantic card in
PCI slot 2.  It exposes 63 VFs per port (max_vfsc).  Here see the
devices get named

onboard: emX
add-in card: pci2#0, pci2#1
VFs there: pci2#0_0, pci2#1_62

Thanks,
Matt

That does seem like the best separator available.

That also fits the mnemonic Ethernet on Motherboard, which is nice.

With the presence of the pci_slot driver to allow association of the PCI address 
with a "slot name" is encoding such information into the interface name really 
necessary?

I think so.  1) Dell systems seem not to be able to put information
into pci_slot.  That needs investigation.  2) if it's not in the name,
the user must do the correlation themselves manually.
