When I was trying to modify the tx timestamping feature, I found that running "./txtimestamp -4 -C -L 127.0.0.1" didn't reflect the error: I succeeded to generate timestamp stored in the skb but later failed to report it to the userspace (which means failed to put css into cmsg). It can happen when someone writes buggy codes in __sock_recv_timestamp(), for example.

Willem, thoughts?
