Commit d14e078f23cc ("net: marvell: mvpp2: only reprogram what is necessary on mac_config") disabled auto negotiation bypass completely, which breaks platforms enabling bypass via firmware (not the best option, but it worked). Since 1000BaseX/2500BaseX ports neither negotiate speed nor duplex mode we could enable auto negotiation bypass to get back information about link state.
