I do not see how it will solve the issue raised by David: hard_start_xmit does not disable irq and takes nearly no lock, thus it can be interrupted if a random irq event happens on a different device. Assume that the driver of the said different device issues a printk through netconsole and the game is over. Without extra locking, netpoll_send can not know that the interrupted hard_start_xmit has left the device/driver in a sane state. -- Ueimor - 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
