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

Hi Andi, This patch series implements the Linux Xen guest as a paravirt_ops backend. The features in implemented this patch series are: * domU only * UP and SMP guest support (NEW!) * dynamic ticks (NEW!) * writable pagetables, with late pinning/early unpinning (no shadow pagetable support) * supports both PAE and non-PAE modes (non-PAE may be broken at the moment) * xen hvc console
