       dev_set_allmulti - update allmulti count on a device


       void dev_set_allmulti  (struct net_device * dev, int inc);


       dev    device

       inc    modifier


       Add  or remove reception of all multicast frames to a device. While the
       count in the device remains above zero the interface remains  listening
       to  all interfaces. Once it hits zero the device reverts back to normal
       filtering operation. A negative inc value is used to drop  the  counter
       when releasing a resource needing all multicasts.
