> Instead of assuming that each VF has pointer to port representor save it in
> xarray. It will allow adding port representor for other device types.
> 
> Drop reference to VF where it is use only to get port representor. Get it from
> xarray instead.
> 
> The functions will no longer by specific for VF, rename them.
> 
> Track id assigned by xarray in port representor structure. The id can't be
> used as ::q_id, because it is fixed during port representor lifetime.
> ::q_id can change after adding / removing other port representors.
> 
> Side effect of removing VF pointer is that we are losing VF MAC information
> used in unrolling. Store it in port representor as parent MAC.
