I wonder if it's an option to use low priority QoS fields for these acks (heck I don't even know if ACKs have such fields in their packet) so that they can get dropped if there are more packets then there is bandwidth .... -- if you want to mail me at work (you don't), use arjan (at) linux.intel.com Test the interaction between Linux and your BIOS via http://www.linuxfirmwarekit.org - 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
