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: -

This is based on an earlier patch from Eric Biederman adding forwarding between macvlans. I extended his approach to allow the administrator to choose the mode for each macvlan, and to implement a functional VEPA between macvlan. Still missing from this is support for communication between the lower device that the macvlans are based on. This would be extremely useful but as others have found out

This series is mainly for testing live migration between 2 vdpa_sim_blk devices. The first patch is preparation and moves the buffer allocation into devices, the second patch adds the `shared_buffer_mutex` parameter to vdpa_sim_blk to use the same ramdisk for all devices. Tested with QEMU v8.0.0-rc2 in this way: modprobe vhost_vdpa modprobe vdpa_sim_blk shared_backend=true vdpa dev add mgmtdev

Second version, all feedback so far addressed, thanks for the help and interest! The patch to iproute2 has not changed, so I'm not including it this time. Patch 4/4 (the netlink interface) is basically unchanged as well but included for completeness. The other changes have moved forward a bit, to the point where I find them a lot cleaner and am more confident in the code being ready for

Not many changes this time, just integrated a bug fix and all the coding style feedback from Eric Dumazet and Patrick McHardy. I'll keep the patch for network namespaces on the tx path out of this series for now, because the discussion is still ongoing and it addresses an unrelated issue. --- Version 2 description: The patch to iproute2 has not changed, so I'm not including it this

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
