Subject: skb processing in SMP kernel

Hi there,

I'm looking at file /usr/src/linux/net/core/dev.c
function "int netif_rx(struct sk_buff *skb)"
and following line:
 
queue = &__get_cpu_var(softnet_data);

Is it possible to put skb into the queue of another CPU then the one
servicing the interrupt? (Disclaimer: Yeah, I know it's probably not
the smartest thing to do because of locks and cache line bounces). How
could it be accomplished? Any lead, comment, link appreciated.


pozdrawiam
