I''m trying to configure dsmark qdisc on 2.6.11.4 user mode linux and tc from iproute2-2.6.11-050314. I think I have some mismatch in my setup since adding dsmark qdisc fails *unless* I specify "set_tc_index" argument which I believe should be optional: # tc qdisc add dev eth1 handle 1:0 root dsmark indices 8 RTNETLINK answers: Invalid argument Mar 20 13:00:50 user user.debug

V3: drop debugging printk's update selinux perm table as well V2: drop patch 1/2, export ifindex directly Redesign netlink attributes Improve netlink seq check Handle IPv6 addr as well This patch exports bridge multicast database via netlink message type RTM_GETMDB. Similar to fdb, but currently bridge-specific. We may need to support modify multicast database too

From: Cong Wang <amwang at redhat.com> V4: remove some useless #include some coding style fix V3: drop debugging printk's update selinux perm table as well V2: drop patch 1/2, export ifindex directly Redesign netlink attributes Improve netlink seq check Handle IPv6 addr as well This patch exports bridge multicast database via netlink message type RTM_GETMDB.

Based on net-next. This patch exports port->port_no port->port_id in the end of IFA_INFO_DATA.

Changes since v9: * series re-ordering so make functionality more distinct. Basic vlan filtering is patches 1-4. Support for PVID/untagged vlans is patches 5 and 6. VLAN support for FDB/MDB is patches 7-11. Patch 12 is still additional egress policy. * Slight simplification to code that extracts the VID from skb. Since we now depend on the vlan module, at the time of input skb_tci is

This series of patches provides an ability to add VLANs to the bridge ports. This is similar to what can be found in most switches. The bridge port may have any number of VLANs added to it including vlan 0 priority tagged traffic. When vlans are added to the port, only traffic tagged with particular vlan will forwarded over this port. Additionally, vlan ids are added to FDB entries and become
