mc_count > 0 , Significance of this flag
Hi all ,
My linux board running a pico chip and pc302_emac driver is not allowing a certain range of Multicast addresses , the counters in /proc/net/dev get updated only for 188.8.131.52 , 184.108.40.206 and other address with +65 .
I put some printfs to debug , and see that , the
dev->flags is set not to IFF_ALLMULTI , instead the code goes to dev->mc_count > 0 , where a sethash table function adds only specific , Multicast addresses are allowed.
I just wanted to know as to , where this dev->mc_count is set ? and what significance does it have .
Thanks & regards,
