Subject: bond_compute_features() does not handle devices with different CSUM

kernel version <= 2.6.20.1
file drivers/net/bonding/bonding_main.c
function bond_compute_features()

-----------
  Given a system with two different NIC. One driver sets
        dev->features |=  NETIF_F_HW_CSUM
  the other driver sets
        dev->features |=  NETIF_F_IP_CSUM

  when enslaving the 2 device above, bond_compute_features()
  does not set the intersection of the 2 CSUM
  features (should be NETIF_F_IP_CSUM)
-----------

   should the bond features in the case above include NETIF_F_IP_CSUM
