Ok, I misunderstood it as interface mode change between successive mac_prepare().
If major reconfiguration is certain to happen after every interface mode change,
I will make another small modification in mac_prepare method to set appropriate
pcs_ops for selected interface mode. 
pcs_ops for low speed, however, will just be existing non 10GBASE-R functions renamed.
This will allow us to get rid of old API's for non 10GBASE-R PCS. I hope you are ok with
these changes done in the same patch.
