Provide a callback to validate skb's originating from tcp timewait socks before passing to the device layer. Full socks have a sk_validate_xmit_skb member for checking that a device is capable of performing offloads required for transmitting an skb. With psp, tcp timewait socks will inherit the crypto state from their corresponding full socks. Any ACKs or RSTs that originate from a tcp timewait sock carrying psp state should be psp encapsulated.
