I've tried with both of those kernel versions, though it was pre-compiled rcn <https://rcn-ee.net/> Ubuntu image. Actually, when i enter promisc mode, ip output shows me PROMISC flag on, but kernel log prints out that the same one is ignored :) As it turned out, i've found snippet of source code which actually confirms it (but it's also one year old). static void cpsw_ndo_change_rx_flags(struct net_device *ndev, int flags) { /* * The switch cannot operate in promiscuous mode without substantial * headache. For promiscuous mode to work, we would need to put the * ALE in bypass mode and route all traffic to the host port. * Subsequently, the host will need to operate as a "bridge", learn, * and flood as needed. For now, we simply complain here and * do nothing about it :-) */ if ((flags & IFF_PROMISC) && (ndev->flags & IFF_PROMISC)) dev_err(&ndev->dev, "promiscuity ignored!\n"); /* * The switch cannot filter multicast traffic unless it is configured * in "VLAN Aware" mode. Unfortunately, VLAN awareness requires a * whole bunch of additional logic that this driver does not implement * at present. */ if ((flags & IFF_ALLMULTI) && !(ndev->flags & IFF_ALLMULTI)) dev_err(&ndev->dev, "multicast traffic cannot be filtered!\n"); } -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
