I don't know if that really was Dave's reason to handle it in a driver. > Could someone give a quick example of when I am wrong and promisc mode > would allow > a NIC to receive a significant number of packets not really destined for > it? In a switched environment it won't have a big effect, I agree. It might help avoid receiving unwanted multicast traffic, which could be more significant than unicast. Anyways, why be wasteful when it can be avoided .. :) - 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
