(#) Get reply timestamp::
bool rxrpc_kernel_get_reply_time(struct socket *sock,
struct rxrpc_call *call,

This allows the timestamp on the first DATA packet of the reply of a
client call to be queried, provided that it is still in the Rx ring. If
successful, the timestamp will be stored into ``*_ts`` and true will be
returned; false will be returned otherwise.
