Hi all,

  Im trying to create four network bridges without physical networks interfaces 
attached under ubuntu server 8.04.1 amd64. Every time that I do 'ifup 
vmbr[0,1,2,3]' I see this message error:

  vmbr0: Dropping NETIF_F_UFO since no NETIF_F_HW_CSUM feature

  .. for every bridge that I need to create. But worst is when system goes up: 
it is terrible slowly when network configuration starts ... and returns same 
error ...

  My /etc/network/interfaces is:

  auto vmbr0
iface vmbr0 inet manual
         pre-up brctl addbr vmbr0
         post-down brctl delbr vmbr0
         up ip link set vmbr0 up
         bridge_fd 0
         bridge_hello 0
         bridge_stp off

  All bridges are configured like this ... what am I doing wrong??
