Other argument: ipw2200 hase this issue becouse it do not support
hardwarescan. so it should be done by CPU. ipw3945 use hardware scan by
default, and wie should probably do not bother about CPU any more. See:
linux-2.6/drivers/net/wireless/iwlwifi/iwl3945-base.c:
7875
/* Disabling hardware scan means that mac80211 will perform scans
7876 * "the hard way", rather than using device's scan. */
7877 if (iwl3945_param_disable_hw_scan) {
7878 IWL_DEBUG_INFO("Disabling hw_scan\n");
7879 iwl3945_hw_ops.hw_scan = NULL;
7880 }
the question is: haw are this things done by software mac80211 scan?
