From ae8d2858c54f52dc4df513a818cc4e1257fd9143 Mon Sep 17 00:00:00 2001 From: "Luis R. Rodriguez" Date: Tue, 23 Dec 2008 15:58:40 -0800 Subject: ath9k: consolidate arguments on hw reset HW reset calls pass the same variables or structs which we can obtain easily from ah. Although this also applies during channel changes as we will keep around the ath9k_channel passed as an argument for now. We now also now propagate the hw reset errors down. Signed-off-by: Luis R.

We currently use an array CLOCK_RATE to keep these values per mode and since as only will use A and G we can depend on the band to get the appropriate values. We note that we should be using a different clock rate value for CCK, we can do this in separate patch, currently this is being disregarded and should only affect when we want to change the default ACK/CTS timeout or slot time and stuck with using using 802.11b.

We only keep data we need to provide our own regulatory_hint(), reg_notifier() and information necessary for calibration. Atheros hardware supports 12 world regulatory domains, since these are custom we apply them through the the new wiphy_apply_custom_regulatory(). Although we have 12 we can consolidate these into 5 structures based on frequency and apply a different set of flags that differentiate them on a case by case basis through the reg_notifier(). If CRDA is not found our own custom world regulatory domain is applied, this is identical to cfg80211's except we enable passive scan on most frequencies. Signed-off-by: Luis R.
