Hi all,
I am facing some latency issues, mainly due to timer issues.
I have looked at the timer stats and I can see several timers coming
from the bridge.
In fact, I do not understand this piece of code :
In net/bridge/br_if.c in function new_bridge_dev there is an
unconditionnal call to br_stp_t

Hi there !
I am facing a jitter issue that I will try to explain :
I have the following configuration :
(A) eth0 <--> br0 <--> eth1 (B)
I have a small and custom kernel (I removed netfilter, for instance) and I
am measuring the time between A and B (using hardware taps, etc.).
My bandwidth is qu

Hi everybody !
I am trying to understand the "PacketFlow.png" image from the website.
I have several misunderstanding, especially on the "Bridging Decision" circles.
I would like to understand which way a packet takes when the rule on
-A INPUT -j ACCEPT is on, for example. When looking at the pac
It is working.
I have to do this :
ebtables -A INPUT -p 0x8809 -j ACCEPT
ebtables -A FORWARD -p 0x8809 -j ACCEPT
When I send a packet on my first interface, it is going on my second
interface if and only if I have both INPUT and FORWARD.
Thanks for your help !!
JM

Do you think, with your solution, that I should bond eth0 with a

Hi there !
I have connected two ethernet 1000Mbps interfaces to my routers, and I
have built a bridge between them :
eth1 <---> br0 <---> eth2
When I am transmitting UDP, ADP, ARP or any other type of frames, I
don't have any problem.
But when, the router sends LACP packets, it is not transmitted

Hi there !
I keep trying to use the ulog/netlink system to receive only the
packets I'm interested by and bridging everything else...
I have a problem using this, because of a too small buffer ?
I am using the recvfrom as the example given on the website, and I am
getting a "no space buffer avail
I will correct myself : I had an error in my socket creation...
This is correctly working, the test_ulog example is easy to
understand, and very useful.
Thanks again !
Best Regards,
JM

I have been looking to the ebtables website, and in particular to the
