      mac80211: separate encoding/bandwidth from flags · da6a4352
      Johannes Berg 提交于
      We currently use a lot of flags that are mutually incompatible,
      separate this out into actual encoding and bandwidth enum values.
      
      Much of this again done with spatch, with manual post-editing,
      mostly to add the switch statements and get rid of the conversions.

      The warning was bogus.  But the conditionals were rather complicated,

      mac80211: convert HW flags to unsigned long bitmap · 30686bf7
      Johannes Berg 提交于
      As we're running out of hardware capability flags pretty quickly,
      convert them to use the regular test_bit() style unsigned long
      bitmaps.
      
      This introduces a number of helper functions/macros to set and to
      test the bits, along with new debugfs code.
      
      The occurrences of an explicit __clear_bit() are intentional, the
      drivers were never supposed to change their supported bits on the
      fly. We should investigate changing this to be a per-frame flag.

      Johannes Berg 提交于
      This support is essentially useless as typically networks are encrypted,
      frames will be filtered by hardware, and rate scaling will be done with
      the intended recipient in mind. For real monitoring of the network, the
      monitor mode support should be used instead.
      
      Removing it removes a lot of corner cases.

      mwl8k: remove nonstandard rate 72 Mbps · 3f524559
      Jonas Gorski 提交于
      This rate causes an overflow in the extended rates IE's data rate field,
      with the overflowing bit setting the Basic Rate Set membership. This
      results in a bogus 8 Mpbs basic rate, making clients checking them refuse
      association.
      
      Since the rate is likely unused anyway (HT will yield better rates between
      supporting chips), we can just remove it.
      
      This fixes association from wpa_supplicant and Android 4.x and newer.

      mwl8k: always apply configuration even when device is idle · fe21bb02
      Jonas Gorski 提交于
      Fix settings not being applied when the device is idle and the firmware
      gets reloaded (because of changing from STA to AP mode). This caused
      the device using the wrong channel (and likely band), e.g. a 5 GHz only
      card still defaulted to channel 6 in the 2.4 GHz band when left
      unconfigured.
      
      This issue was always present, but only made visible with "mwl8k: Do not
      call mwl8k_cmd_set_rf_channel unconditionally" (0f4316b9), since before
      that the channel was (re-)configured at the next _config call even when
      it did not change from the mac80211 perspective.

      Currently the caps are parsed on every firmware reload, causing any

      When there is a firmware to interface mode mismatch, the triggered
      firmware reload causes a reset of the regulatory settings, causing all

      To prevent this, only parse the caps on the first firmware load during
      hardware probe, and store them locally to know we have already parsed
      them.

      mwl8k: fix band for supported channels · d786f67e
      Jonas Gorski 提交于
      The band field for the supported channels were left unpopulated, making
      them default to 0 == IEEE80211_BAND_2GHZ, even for the 5GHz channels.
      
      This resulted in null pointer accesses if anything tries to access
      wiphy->bands[channel->band] of a 5GHz channel on 5GHz only cards, since
      wiphy->bands[2GHZ] is NULL for them (e.g. cfg80211_chandef_usable does).
      
      Example kernel OOPS:
