[ Upstream commit 8e0a754b0836d996802713bbebc87bc1cc17925c ]
Airoha_eth driver forwards offloaded uplink traffic (packets received on GDM1 and forwarded to GDM{3,4}) to GDM2 in order to apply hw QoS. This is correct if the device does not support a dedicated GDM2 port. In this case, in order to enable hw offloading for uplink traffic, the packets should be sent to GDM{3,4} directly.
