[Bridge] Lost TCP packet
...$i++) { hping2 -q -c 1 -d $data_len -E
random.file 10.0.0.10 }
My problem is that some packets are lost.
Here is my setup:
PC1 (10.0.0.1) ===== BR1 --------- BR2 ===== PC2 (10.0.0.10)
After analysis, i determined that these packets were lost because one
of the two bridges was in BR_STATE_DISABLED state when the lost packet
arrived.
In fact, the packet is thrown by the bridge because, in
br_input.c::br_handle_frame(), state==BR_STATE_DISABLED which force
the code to jump to the err: tag at the end of this function.
The state is set to this value while an event is received inside

[Bridge] [PATCHv4 net-next 0/2] Add two new flags to bridge.
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.

[Bridge] bridge problem when one interface is in blocking mode
Hi,
We have a simple bridge setup but the ping (and other
network traffic) does not work reliably. After tracing
the code, it looks like a software bug. Since bridge
software is been running by thousands of people. I
guess I am wrong. Anyway, here is the problem.
There are 2 boxes and each one has 2 interfaces, 1
ethernet and 1 wifi. STP is enabled for the bridge to
avoid the loop. So the box 1

[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

[Bridge] [PATCH v10 net-next 00/12] VLAN filtering/VLAN aware bridge
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
