Ho this is much clearer now, I realize I got confused by the previous version
of this patch...
As we've seen, .port_set_cmode is only called from mv88e6xxx_port_setup_mac and
.phylink_config_mac, so it is fine to keep this "make writable" code private
to the mv88e6341_port_set_cmode implementation. I will send a follow-up
patch which addresses that and removes the .port_set_cmode_writable operation.
Thank you,
Vivien
