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=3D17 192.168.0.43:137 192.168.0.255:137 L=3D78 S=3D0x00 I=3D387 F=3D0x0000 T=3D128 nf_hook: hook 1 already set. skb: pf=3D2 (unowned) dev=3Dbr0 len=3D78 PROTO=3D17 192.168.0.43:137 192.168.0.255:137 L=3D78 S=3D0x00 I=3D387 F=3D0x0000 T=3D128 ... 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.
