Subject: RE: [PATCH net-next] netxen: write IP address to firmware when
 using bonding

Hi Andy,

We need to restore the ip address after the adapter reset.
netxen_restore_indev_addr is the function that restores normal ip addresses
and vlan ip addresses. If we could find bond device directly from slave then 
we can use netxen_config_indev_addr to add the ip address of the bond device.
Otherwise we may need to cache the bond ip address in function netxen_list_config_vlan_ip
and change the condition from

if (!is_vlan_dev(dev))
                return;

to

if (!is_vlan_dev(dev) && !is_bond_dev(dev))
                return;


Some of the code in if and else part is repeated.
If possible can we have small functions for that ?
eg:
if (!is_netxen_netdev(dev))
+                       goto done;
+
+               adapter = netdev_priv(dev);
+               if (!adapter)
+                       goto done;
+
+               if (adapter->is_up != NETXEN_ADAPTER_UP_MAGIC)
+                       goto done;
+
+               netxen_config_indev_addr(adapter, orig_dev, event);

Yes, some helper that walks the device list and tries to find
a device whose ->master matches 'dev'.
