Update allmulti count on a device
Usage
int dev_set_allmulti(struct net_device * dev, int inc);
Arguments
dev
device
inc
modifier
Overview
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.
