To an extent, but not entirely.
Currently, the assigned MAC address and (optional) VLAN tag for each
networking VF are configured via the PF net device (though this is done
though the rtnetlink API rather than ethtool).
I actually have a use-case where the guest needs to be able to modify
the MAC addresses of network devices that are actually VFs.
The guest is bonding the network devices together, so the bonding driver
in the guest expects to be able to set all the slaves to the same MAC
address.
As I read the ixgbe driver, this should be possible as long as the host
hasn't explicitly set the MAC address of the VF. Is that correct?
