    [TG3]: 5780 PHY fixes · c94e3941
    Michael Chan authored
    Fix 5780 PHY related problems:
    
    1. MAC_RX_MODE reset must be done before setting up the MAC_MODE
       register on 5705_PLUS chips or the chip will stop receiving after
       a while. The MAC_RX_MODE reset is needed to prevent intermittently
       losing the first receive packet on serdes chips.
    
    2. Skip MAC loopback test on 5780 because of hardware errata. Normal
       traffic including PHY loopback is not affected by the errata.
    
    3. PHY loopback fails intermittently on 5708S and this is fixed by
       putting the PHY in loopback mode first before programming the MAC
       mode register. A MAC_RX_MODE reset is also added.
    
    4. Return -EINVAL in tg3_nway_reset() if device is in TBI mode. Allow
       nway_reset if 5780S is in parallel detect mode.
    
    5. Add missing PHY IDs in KNOWN_PHY_ID() macro.
