NAME
dev_set_allmulti - update allmulti count on a device
SYNOPSIS
int 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. Return 0 if successful
or a negative errno code on error.
