It can be dequeed with rcu protection even. in my case i had a dev->blist where the stack queued. You really want to avoid requeueing altogether. The trick i used is to have the driver tell you how many packets you can pull off the qdisc. cheers, jamal - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
