The delay will be just shifted to the > moment when first DHCP/TCP/whatever negotiation happens. Until the link is up, the packet scheduler just holds onto packets and queued them up. When the link comes up, this queue is released and the packets sent out. That's why it's beneficial to wait some time until the link comes up before we start sending stuff out. Because otherwise any timeouts used will be inaccurate. This could code be spiffed up to wait for the link up indication on devices it cares about. Feel free to code that up :-) -- To unsubscribe from this list: send the line "unsubscribe linux-embedded" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
