That sounds great but for what whould you like to use? It may help me 
for the implementation. Currently it is not available since the the 
net_device structure holds the group id and for this get operation an 
iteration (of net_devices) may be necessary...

We didn't want to use multiple groups in favour of masked group ids. 
What kind of usage needs other implementation?
