With regard to 2.6.11-rc4 (and probably others).

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.


Thanks, Ben
