I just noticed something that struck me as a bit strange. Might be per design though... If you set the IP_TOS and then the SO_PRIORITY for a socket, the TOS is what you set it to, and so is the priority. However, if you set the PRIORITY (to 55, in my case) and then set the IP_TOS (to 3, in my case), then the priority will be re-set to 0. My opinion is that setting the IP_TOS should not affect the priority, especially if it has already been specifically set on that socket.
