Practice shows this. It's as simple as that.

I don't think the type of device influences whether packets are dropped inside of some random kernel subsystem. -- Greetings, Michael. _______________________________________________ Bcm43xx-dev mailing list [email protected] https://lists.berlios.de/mailman/listinfo/bcm43xx-dev
