Hi Guenter, > Interesting question. Does the underlying network device support VLAN HW > acceleration (NETIF_F_HW_VLAN_CTAG_RX, NETIF_F_HW_VLAN_CTAG_TX) ?
Yes, in our case, it's an IGB device. I also set the DSA slave_dev->features and slave_dev->vlan_features to master->vlan_features | NETIF_F_VLAN_FEATURES | NETIF_F_HW_SWITCH_OFFLOAD, not sure if it is good or not. > If yes, the dsa code may need to move the tag into the header. > If we are lucky, a call to vlan_hwaccel_push_inside() might do it. Thanks, I'm currently looking into it and doing some tests, I'm coming back to you asap. > Do you have some vlan dsa code to share, by any chance ? That might > save me some time, as I am looking into it as well. Yes, I am about the send an RFC for fully integrated 802.1q VLAN support on Marvell 88E6352 devices.
