DEV_OPEN(9) Network device support DEV_OPEN(9) 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. COPYRIGHT Kernel Hackers Manual 3.11 November 2013 DEV_OPEN(9)[top]
