SYNOPSIS
int dev_set_allmulti(struct net_device * dev, int inc);
ARGUMENTS
dev

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. Return 0 if
successful or a negative errno code on error.
