dev_set_promiscuity — update promiscuity count on a device
int dev_set_promiscuity ( | struct net_device * dev, |
int inc); |
Add or remove promiscuity from a device. While the count in the device remains above zero the interface remains promiscuous. Once it hits zero the device reverts back to normal filtering operation. A negative inc value is used to drop promiscuity on the device. Return 0 if successful or a negative errno code on error.
