Interesting idea. I'll look and see if there are any bitfield differences between the 7512 and 7514.

Oh, nice. Thanks. By the end of all this it feels like there'll be nothing left in this file (in a good way!) There might be more implications for me regarding commit 79fda660bdbb ("net: dsa: ocelot: populate supported_interfaces") since it seems to be based on the assumption that every sub-driver only supports a single interface mode. I still have my homework to do there though. > > > + > > + phylink_set_port_modes(mask); > > + > > + phylink_set(mask, Pause); > > + phylink_set(mask, Autoneg); > > + phylink_set(mask, Asym_Pause); > > + phylink_set(mask, 10baseT_Half); > > + phylink_set(mask, 10baseT_Full); > > + phylink_set(mask, 100baseT_Half); > > + phylink_set(mask, 100baseT_Full); > > + phylink_set(mask, 1000baseT_Half); > > + phylink_set(mask, 1000baseT_Full); > > + > > + bitmap_and(supported, supported, mask, __ETHTOOL_LINK_MODE_MASK_NBITS); > > + bitmap_and(state->advertising, state->advertising, mask, > > + __ETHTOOL_LINK_MODE_MASK_NBITS); > > +} > > + > > +static struct vcap_props vsc7512_vcap_props[] = { > > Why not vsc7514_vcap_props? > > > + [VCAP_ES0] = { > > + .action_type_width = 0, > > + .action_table = { > > + [ES0_ACTION_TYPE_NORMAL] = { > > + .width = 73, > > + .count = 1, > > + }, > > + }, > > + .target = S0, > > + .keys = vsc7514_vcap_es0_keys, > > + .actions = vsc7514_vcap_es0_actions, > > + }, > > + [VCAP_IS1] = { > > + .action_type_width = 0, > > + .action_table = { > > + [IS1_ACTION_TYPE_NORMAL] = { > > + .width = 78, > > + .count = 4, > > + }, > > + }, > > + .target = S1, > > + .keys = vsc7514_vcap_is1_keys, > > + .actions = vsc7514_vcap_is1_actions, > > + }, > > + [VCAP_IS2] = { > > + .action_type_width = 1, > > + .action_table = { > > + [IS2_ACTION_TYPE_NORMAL] = { > > + .width = 49, > > + .count = 2, > > + }, > > + [IS2_ACTION_TYPE_SMAC_SIP] = { > > + .width = 6, > > + .count = 4, > > + }, > > + }, > > + .target = S2, > > + .keys = vsc7514_vcap_is2_keys, > > + .actions = vsc7514_vcap_is2_actions, > > + }, > > +};

Communication to external phys is also functional, but the SGMII / QSGMII interfaces are currently non-functional.
