The following series adds 2 new flags to bridge. One flag allows the user to control whether mac learning is performed on the interface or not. By default mac learning is on. The other flag allows the user to control whether unicast traffic is flooded (send without an fdb) to a given unicast port. Default is on. Changes since v4: - Implemented Stephen's suggestions. Changes since v2: -

hi i tried the example given on the examples page to duplicate selected traffic like tc qdisc add dev eth0 root handle 1: prio tc qdisc add dev eth0 parent 1:3 handle 3: netem duplicate 40% tc filter add dev eth0 protocol ip parent 1:0 prio 3 u32 match ip dst 11.0.2.2 flowid 1:3 when i ping from 11.0.2.2 to this interface my machine hangs. the same thing works for drop or delay. i would

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

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

When I was preparing Xen''s netback driver for upstream one of the things I removed was the zero-copy guest transmit (i.e. netback receive) support. In this mode guest data pages ("foreign pages") were mapped into the backend domain (using Xen grant-table functionality) and placed into the skb''s paged frag list (skb_shinfo(skb)->frags, I hope I am using the right
