    [NET]: Initialize the network namespace of network devices. · 6d34b1c2
    Eric W. Biederman 提交于
    Except for carefully selected pseudo devices all network
    interfaces should start out in the initial network namespace.
    Ultimately it will be register_netdev that examines what
    dev->nd_net is set to and places a device in a network namespace.
    
    This patch modifies alloc_netdev to initialize the network
    namespace a device is in with the initial network namespace.
    This gets it right for the vast majority of devices so their
    drivers need not be modified and for those few pseudo devices
    that need something different they can change this parameter
    before calling register_netdevice.
    
    The network namespace parameter on a network device is not
    reference counted as the devices are inside of a network namespace
    and cannot remain in that namespace past the lifetime of the
    network namespace.
