Hi All, There is a nice feature (I saw it on 3Com EtherLink Server NIC cards) called "TCP Segmentation Offload". Which means that the stack is presented with a larger MTU than eth, and the NIC produces smaller tcp segments. More info at M$ http://www.microsoft.com/HWDEV/network/taskoffload.htm#Segment I would like to hear your comments, weather this is something that can gain real performance, and how to incorporate this into the Linux stack (At least I didn't see any references to it in kernel 2.4.(x<4)). deca // sizeof(void) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
