[Xen-devel] event notify during netfront and netback setup in Xen3.1

["Zang Hongyong" <zanghongyong@xxxxxxxxxx>]

hi
In Xen3.1 source
when setup
  netfront: when netback changed XenBusState to InitWait, fuction 
network_connect() called
            in network_connect(),notify_remote_via_irq() was called, which 
gives netback a kick.
            then netfront changed Xenbusstate to Connected

  but at the same time, netback has not bind its eventchannel to netfront 
domain's event?
  so how could this happen, when netback receive event from netfront domain? 

ps:
The event bind happens when netfront Connected, netback calls connect() 
-->connect_rings() -->netif_map() . And later changed XenbusState to Connected.
After all Connected, netback and netfront setup over and begin tx and rx in 
common.
