[PATCH RFC (resend) net-next 0/6] virtio-net: Add support for virtio-net header extensions
Curreclty virtion net header is fixed size and adding things to it is rather
difficult to do. This series attempt to add the infrastructure as well as some
extensions that try to resolve some deficiencies we currently have.
First, vnet header only has space for 16 flags. This may not be enough
in the future. The extensions will provide space for 32 possbile extension
flags and 32 possible

[Bridge] RE: [VLAN] Re: [PATCH/RFC] Let {ip, arp}tables "see" bridged VLAN tagged{I,AR}P packets
...kets
tcpdump works (and Ethereal for Windows sees the packet correctly on the
wire) so the problem doesn't occur when sending packets. I added following
line to vlan_dev.c:
vlan_dev.c:: int vlan_skb_recv(struct sk_buff *skb, struct net_device *dev,
struct packet_type* ptype):
vlan_TCI = ntohs(vhdr->h_vlan_TCI);
+ /* Print the 802.1p priority */
+printk("VLAN Prio: %hx\n", vlan_TCI >> 13);
vid = (vlan_TCI & VLAN_VID_MASK);
With the code above I get the 802.1p correctly. Does anyone know how and
when pcap grabs the packet (does pcap grab the packet before or after
vla...

[Bridge] [PATCH net-next V5 00/14] Add basic VLAN support to bridges
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
