Move common fields for queue management to struct nf_info and rename it to struct nf_queue_entry. The avoids one allocation/free per packet and simplifies the code a bit. Alternatively we could add some private room at the tail, but since all current users use identical structs this seems easier. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.
