SmartNIC DPUs may not expose some privileged eswitch operations
to the hypervisor hosts. For example, this happens with Bluefield
devices running in the ECPF (default) mode for security reasons. While
VF MAC address programming is possible via an RTM_SETLINK operation,
trying to set a VLAN ID in the same operation will fail with EPERM.
The equivalent ip link commands below provide an illustration:
1. This works:
sudo ip link set enp130s0f0 vf 2 mac de:ad:be:ef:ca:fe
2. Setting (or clearing) a VLAN fails with EPERM:
sudo ip link set enp130s0f0 vf 2 vlan 0
RTNETLINK answers: Operation not permitted
3. This is what Libvirt attempts to do today (when trying to clear a
VF VLAN at the same time as programming a VF MAC).
sudo ip link set enp130s0f0 vf 2 vlan 0 mac de:ad:be:ef:ca:fe
RTNETLINK answers: Operation not permitted
If setting an explicit VLAN ID results in an EPERM, clearing a VLAN
(setting a VLAN ID to 0) can be handled gracefully by ignoring the
EPERM error with the rationale being that if we cannot set this state
in the first place, we cannot clear it either.
In order to keep explicit clearing of VLAN ID working as it used to
be passing a NULL pointer for VLAN ID is used.

Commit 795e9e05c3 (libvirt-7.7.0) refactored the code in virpci.c and
virnetdev.c that gathered lists of the Virtual Functions (VF) of an
SRIOV Physical Function (PF) to simplify the code.
Unfortunately the simplification made the assumption, in the new
function virPCIGetVirtualFunctionsFull(), that a VF's netdev
interface name should only be retrieved if the PF had a valid
phys_port_id. That is an incorrect assumption - only a small handful
of (now previous-generation) Mellanox SRIOV cards actually use
phys_port_id (this is for an odd design where there are multiple
physical network ports on a single PCI address); all other SRIOV cards
(including new Mellanox cards) have a file in sysfs called
phys_port_id, but it can't be read, and so the pfPhysPortID string is
NULL.
The result of this logic error is that virtual networks that are a
pool of VFs to be used for macvtap connections will be unable to
start, giving an errror like this:
VF 0 of SRIOV PF enp130s0f0 couldn't be added to the interface pool because it isn't bound to a network driver - possibly in use elsewhere
This error message is misinformed - the caller of
virNetDevGetVirtualFunctionsFull() only *thinks* that the VF isn't
bound to a network driver because it doesn't see a netdev name for the
VF in the list. But that's only because
virNetDevGetVirtualFunctionsFull() didn't even try to get the names!
We do need a way for virPCIGetVirtualFunctionsFull() to sometimes
retrieve the netdev names and sometimes not. One way of doing that
would be to send down the netdev name of the PF whenever we also want
to know the netdev names of the VFs, but send a NULL when we
don't. This can conveniently be done by just *replacing* pfPhysPortID
in the arglist with pfNetDevName - pfPhysPortID is determined by
simply calling virNetDevGetPhysPortID(pfNetDevName) so we can just
make that call down in virPCIGetVirtualFunctionsFull() (when needed).
This solves the regression introduced by commit 795e9e05c3, and also
nicely sets us up to (in a subsequent commit) move the call to
virNetDevGetPhysPortID() down one layer further to virPCIGetNetName(),
where it really belongs!

To accomplish this the function is renamed to
'virPCIGetVirtualFunctionsFull' while keeping a wrapper with original
name and if the physical port ID is passed the interface name is fetched
too without the need to re-convert the address into a sysfs link.
For now 'virNetDevGetVirtualFunctions' still converts the returned data

Some SRIOV PFs don't have a netdev associated with them (the spec
apparently doesn't require it). In most cases when libvirt is dealing
with an SRIOV VF, that VF must have a PF, and the PF *must* have an
associated netdev (the only way to set the MAC address of a VF is by
sending a netlink message to the netdev of that VF's PF). But there
are times when we don't need for the PF to have a netdev; in
particular, when we're just getting the Switchdev Features for a VF,
we don't need the PF netdev - the netdev of the VF (apparently) works
just as well.
Commit 6452e2f5 (libvirt 5.1.0) *kind of* made libvirt work around PFs
with no netdevs in this case - if virNetDevGetPhysicalFunction
returned an error when setting up to retrieve Switchdev feature info,
it would ignore the error, and then check if the PF netdev name was
NULL and, if so it would reset the error object and continue on rather
than returning early with a failure. The problem is that by the time
this special handling occured, the error message about missing netdev
had already been logged, which was harmless to proper operation, but
confused the user.
Fortunately there are only 2 users of virNetDevGetPhysicalFunction, so
it is easy to redefine it's API to state that a missing netdev name is
*not* an error - in that case it will still return success, but the
caller must be prepared for the PF netdev name to be NULL. After
making this change, we can modify the two callers to behave properly
with the new semantics (for one of the callers it *is* still an error,
so the error message is moved there, but for the other it is okay to
continue), and our spurious error messages are a thing of the past.

that we have extra verbosity/boilerplate to retrieve an information that

A better way is presented by virNVMEDeviceNew(), where the caller just
supplies a virPCIDeviceAddress pointer and the function handles the

This incorrect code has been here since the function was originally

- the items at those indexes in tb are IFLA_ADDRESS and IFLA_BROADCAST
