NAME¶
dev_open - prepare an interface for use.SYNOPSIS¶
int
dev_open(struct net_device * dev);
ARGUMENTS¶
devdevice 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¶
