Hi,
According to the man page socket(7), setting SO_PRIORITY (and
hence sk->sk_priority) on a socket should alter the TOS field of the
outgoing packets. However, in linux-2.6.14, the code in
net/ipv4/ip_output.c:ip_queue_xmit fills the value of the IP header's
tos using inet->tos (which is set using the IP_TOS socket options). I
want to say that sk_priority is used for local queues only and IP_TOS
needs to be set for actually modifying the outgoing packets' TOS. Is
this the case?
