Re: bridge loop without physical loop

2002-07-02 Thread Luigi Rizzo
bridging is incompatible with cards which hear their own transmissions (~IFF_SIMPLEX). I am not sure if the "ep" is one of this kind. if you do an 'ifconfig' and you do not see the 'SIMPLEX' flag set for the card, then you can suspect that. I should probably put code in the bridging code to make

2002-07-02 Thread Kenneth Ingham
I'm having a problem where the bridging code seems to be doing weird things. To eliminate the possibility of a real loop, the second ethernet interface is connected to a hub with no machines on it. However, I am still seeing messages like: Jun 30 16:24:48 zprime /kernel: -- loop (0) 00.60.97.88

Hi, you can read the numbers I posted as you like, but in the non-SMP case performance is not "seemingly" better, it IS better. Before people think differently: the code i posted is _perfectly safe_ to use under the assumption that I used -- i.e. that you hold Giant when manipulating t

There are several problems with your "simple" code that make it simpler than what's in -CURRENT and in -STABLE and therefore yield [obviously] seemingly better times. 1) sleeping in the case of a system exhausted of mbufs and clusters is now broken because code that frees to this "combined"
