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.
