NAME

       dev_set_allmulti - update allmulti count on a device

SYNOPSIS

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

ARGUMENTS

       dev    device

       inc    modifier

DESCRIPTION

       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.
