Hi all,
I recently discovered that when I am using brctl in
my product, I got some troubles with a driver which need to quickly handle
interrupts. Brct seems to "mask interrupts" for long time - more than
6 ms - when there is ethernet traffic in it.
I also noticed that there is a lot of messages on
the console when there is trafic in the bridge.Here a sample of messages
:
...
PROTO=17 192.168.0.43:137 192.168.0.255:137
L=78 S=0x00 I=387 F=0x0000 T=128
nf_hook: hook 1 already set. skb: pf=2 (unowned) dev=br0 len=78 PROTO=17 192.168.0.43:137 192.168.0.255:137 L=78 S=0x00 I=387 F=0x0000 T=128 ...
Maybe these two things are linked ?
These messages are quite boring but this is not my
real problem. My problem is the enormous interrupt latency that brctl bring in
my product.
My product runs with a linux 2.4.27 for
arm.
Is what happens in my product normal ?
Is there any magical patch for my problem
?
Thanks all,
bye.
Irénée B.
