cfg80211: remove enum ieee80211_band

2016-04-12T13:56:15+00:00

This enum is already perfectly aliased to enum nl80211_band, and the only reason for it is that we get IEEE80211_NUM_BANDS out of it. There's no really good reason to not declare the number of bands in nl80211 though, so do that and remove the cfg80211 one. Signed-off-by: Johannes Berg

carl9170: Convert byte_rev_table uses to bitrev8

2014-10-30T19:26:52+00:00

Use the inline function instead of directly indexing the array. This allows some architectures with hardware instructions for bit reversals to eliminate the array. Signed-off-by: Joe Perches Signed-off-by: John W. Linville

carl9170: remove fast channel change feature

2013-03-27T17:37:37+00:00

Marco Fonseca reported a issue with his carl9170 device: "I'm seeing a problem with the carl driver. If I change channels repeatedly on the 2.4ghz band, monitoring (e.g. tcpdump) will eventually halt. I've seen this on various versions of the carl driver/firmware (both from 1.9.4 to 1.9.7)" The culprit was identified as "fast channel change feature" which according to Adrian Chadd is: "... notoriously unreliable and really only fully debugged on some very later chips." Therefore, this patch removes the fast channel change feature. The phy will now always have to go through a cold reset when changing channels, but it should no longer become deaf.

mac80211: Use a cfg80211_chan_def in ieee80211_hw_conf_chan

2013-03-25T18:19:35+00:00

Drivers that don't use chanctxes cannot perform VHT association because they still use a "backward compatibility" pair of {ieee80211_channel, nl80211_channel_type} in ieee80211_conf and ieee80211_local. Signed-off-by: Karl Beldan [fix kernel-doc] Signed-off-by: Johannes Berg

carl9170: allow users to lower output power level

2012-01-27T19:56:57+00:00

This patch implements a simple way of reducing the output power of the device by a configurable upper limit. Requested-by: Harshal Chhaya Signed-off-by: Christian Lamparter Signed-off-by: John W. Linville

carl9170: improve site survey

The firmware keeps track of channel usage. This data can be used by the automatic channel selection to find the *best* channel.

carl9170: fix timekeeping for HW_COUNTER firmwares

2011-08-24T18:41:42+00:00

AR9170_PWR_REG_PLL_ADDAC is used to set the main clock divisor which affects the AHB/CPU speed. Because this would interfere with the firmware internal timekeeping, the function has to be moved into the firmware. Signed-off-by: Christian Lamparter Signed-off-by: John W. Linville
