Add struct phylink and struct phylink_pcs pointers to phylink_pcs_neg_mode() and pass in the appropriate structures. Set pl->pcs_neg_mode before returning, and remove the return value. This will allow the capabilities of the PCS and any PHY to be used when deciding which pcs_neg_mode should be used.
