( modified ng_etherchannelbonding). But, the receiver is getting the packets out-of-order - as expected, when packets are of different size, but, I am not understanding, why,even when the 2 NICs are identical and packets are of MTU size, reordering is occuring. Any clues welcome. I was trying to see if the reason is the fact that each NIC puts up a lot of packets at a time to the TX DMA Area - and so, is it possible in any way to gain a better contol over the actual sending of packets. _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
