> Currently when there are SR-IOV VF(s) and the user does "ip link show <pf
> interface>" the VF unicast MAC addresses all show 00:00:00:00:00:00
> if the unicast MAC was set via VIRTCHNL (i.e. not administratively set by the
> host PF).
> 
> This is misleading to the host administrator. Fix this by setting the VF's
> dflt_lan_addr.addr when the VF's unicast MAC address is configured via
> VIRTCHNL. There are a couple cases where we don't allow the
> dflt_lan_addr.addr field to be written. First, If the VF's pf_set_mac field is
> true and the VF is not trusted, then we don't allow the dflt_lan_addr.addr to
> be modified. Second, if the dflt_lan_addr.addr has already been set (i.e. via
> VIRTCHNL).
> 
> Also a small refactor was done to separate the flow for add and delete MAC
> addresses in order to simplify the logic for error conditions and set/clear the
> VF's dflt_lan_addr.addr field.
