NAME

       dev_open - prepare an interface for use.

SYNOPSIS

       int dev_open  (struct net_device * dev);

ARGUMENTS

       dev    device to open

DESCRIPTION

       Takes  a  device  from  down  to  up  state.  The device’s private open
       function is invoked and then the multicast lists  are  loaded.  Finally
       the  device  is moved into the up state and a NETDEV_UP message is sent
       to the netdev notifier chain.

       Calling this function on an active interface is a nop. On a  failure  a
       negative errno code is returned.
