+A phylink integration is necessary only when the partner DPMAC is not of
+``TYPE_FIXED``. This means it is either of ``TYPE_PHY``, or of
+``TYPE_BACKPLANE`` (the difference being the two that in the ``TYPE_BACKPLANE``
+mode, the MC firmware does not access the PCS registers). One can check for
+this condition using the following helper::
- - bool dpaa2_mac_is_type_fixed(struct fsl_mc_device *dpmac_dev,struct fsl_mc_io *mc_io);
+ - static inline bool dpaa2_mac_is_type_phy(struct dpaa2_mac *mac);
Before connection to a MAC, the caller must allocate and populate the
dpaa2_mac structure with the associated net_device, a pointer to the MC portal
