Subject: Protocol handler for Marvell DSA EtherType packets

Hi Netdev

I writing a new protocol handler using dev_add_pack().  (For a Marvell
switch chip handling DSA (Distributed Switch Architecture) Ethertype
packets).

My protocol handler works and I get the skb. But I want to remove the
DSA Headers and send the packet back for normal processing on a
device. (I actually just want to be able to tcpdump these packets on
the device).

I'm removing the headers by:
  skb_pull(skb, sizeof(struct dsa_header));

I'm trying to retransmit it by:
  netif_rx(skb);

But it seems that I just retransmit the same packet without removing
the DSA headers.

Any hints about which functions I should use the remove the DSA header?
