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).
The code looks good. I don't know much about proper kernel debugging,
so my next step would be e.g. printk'ing the first 16 bytes of
received packets, so you have the ethernet header + the atheros
header, if VLAN is enabled (you should only see the atheros header in
this case).
Right after the "skb_put(skb,len); skb->dev=dev;" I dump the packet.
The packets seems ok (they're without the ar8216 header), *but* I'm only
getting multicast (01:00:5e:00:00:16) or broadcast (ff:ff:ff:ff:ff:ff)
packets, nothing else, e.g.
60 byte frame 01:00:5e:00:00:16 to 00:0b:6a:51:ff:ea type 800
01 00 5e 00 00 16 00 0b 6a 51 ff ea 08 00 46 c0

I see various other mdns or cups browse packet.
I don't see any unicast packet.
