Hi,

I am experimenting with a communications system. In the driver, I receive some packets from higher layers that have extra information in the last 4 bytes. I want to remove those 4 bytes before sending the packet.

I have seen that it is not enough to do a skb_trim(skb, skb->len-4) inside of prism2_tx for those packets.

What else can I do to remove that information? Can somebody give me some hints?

thanks a lot,

Carles
