If you don't want to go that far, just run a bunch of "iwlist eth1 scan" and "iwconfig eth1" over and over and you'll effectively simulate the behavior of NM in this situation (although doing it a lot quicker than NM likely). Setting up a script to just run those two in parallel continuously is probably a good test of any WE locking in a driver :) Dan > Larry - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
