Hello, if a netdevice needs some tailroom to append to an egress skbuff some device-specific trailer, and the skbuff passed to hard_start_xmit() does not have any room left, I assume the skbuff must be copied using skb_copy_expand. Is there any nicer way to expand the tail that can avoid copies? Or better is any way (planned in future kernel relases) that can allow a netdevice to specify to the upper layers that it wants to reserve some tailroom, similar to hard_header_len?
