DEV_SET_PROMISCUITY(9)					      Network device support					    DEV_SET_PROMISCUITY(9)

NAME
       dev_set_promiscuity - update promiscuity count on a device

SYNOPSIS
       int dev_set_promiscuity(struct net_device * dev, int inc);

ARGUMENTS
       dev
	   device

       inc
	   modifier

DESCRIPTION
       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.
