Things were working fine here on Armada 7K/8K even without calling mvpp21_port_power_up(port). But I've looked into more details, and in fact the whole function makes sense on PPv2.2, except the mvpp2_port_fc_adv_enable(port) part of it. So I've replaced this with: mvpp2_port_mii_set(port); mvpp2_port_periodic_xon_disable(port); if (priv->hw_version == MVPP21) mvpp2_port_fc_adv_enable(port); mvpp2_port_reset(port); This will be in my v3. > In any case, the GMAC part is much the same as mvneta, and I think > that code should be shared rather than writing new versions of it. Possibly, but it's really a separate thing: this is completely independent from introducing PPv2.2 support, it's something that already exists. The patch series is already 16 patches long in its v2, and is going to even a bit longer in its v3, so I would really like to stick to just PPv2.2 support. Thanks!
