I figured that the net_tx_action function is the one that schedules packet transmission. I understood a fair portion of the code but for the call to netif_rx (netback.c:1454) after scheduling the tx_response and the update of the rx stats in the transmission function. I also noticed that netif_be_start_xmit function queues the sk_buff passed to it in the receive queue (rx_queue) and schedules the net_rx_tasklet (netback.c:336). Could someone demystify all of this please? Thanks much. - Micky _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
