  Subject: [Xen-devel] Network questions


  Hi,

  Can someone tell me what is the functionality of "backend" in XenoLinux?

  Take the network for example, it seems that all the virtual network interfaces corresponding to 
  guest OS's are created in Xen. And on the receiving side, interrupt VIRQ_NET is raised from 
  Xen upward to XenoLinux. However, it seems that this kind of interrupts are not processed by 
  "backend". 

  So what does "backend" do for networking? For example, functions like 'netif_ctrlif_rx()', 
  'net_rx_action()', 'netif_be_start_xmit()', etc. 

  Thanks!
  Xiaofang
