This is only the half of it, it replaces the TX function, but it can't
overwrite the RX function. So it still needs help from the ethernet
driver. This is where this code comes into play:
if (ag->phy_dev) {
ag->phy_dev->netif_receive_skb(skb);
} else {
skb->protocol = eth_type_trans(skb, dev);
netif_receive_skb(skb);
}
If your architecture isn't ar71xx or atheros, you probably need to
port this for the ethernet driver.
Well, I tried but I failed (unsurprisingly since I know nothing about
Linux network code).
This is a danube based board and this is the patch I tried:

The printks are to see what path the code took, it takes the "correct"
one but still the network doesn't work (but I still can see the arp
entries).
