Re: Fw: issues with SO_PRIORITY and IP_TOS

Hi,
I agree with Alexey in regards to DSCP should be done by classifiers.
Current mode of operation is: Whatever DSCP value you set will be reset
by the network/box manager depending on some criteria they set.  
Applications running as root or sudo can of course open a netlink
connection and set these values via a classifier.

Actually one important thing easy to miss is that the IEEE priorities
are reverse to what the IETF priorities are (who would have thunk, eh?).
I havent looked at the VLAN code however blindly using the
sk/skb->priority is _bad_ given that sk/skb->priority is based on IETF
semantics. I bet you the Linux vlan code doesnt know this.

cheers,
jamal
