Hi: OK, here are the patches to COW TSO packets before the TCP/TCP header gets written over. This one defines a new bit of dataref. It's set just before a packet joins the TCP write queue. It's cleared after the packet is taken off the queue and just before it's freed. Signed-off-by: Herbert Xu <herbert@xxxxxxxxxxxxxxxxxxx> Cheers, -- Visit Openswan at http://www.openswan.org/ Email: Herbert Xu ~{PmV>HI~} <herbert@xxxxxxxxxxxxxxxxxxx> Home Page: http://gondor.apana.org.au/~herbert/ PGP Key: http://gondor.apana.org.au/~herbert/pubkey.txt
