      iwlwifi: enable DC calibration based on config parameter · 178d1596
      Wey-Yi Guy authored
      Different devices have different calibration requirement,
      some need DC calibration and some don't; make it a cfg parameter
      for easy management.

      iwlwifi: name change from signal protection flag · 4e3243f5
      Wey-Yi Guy authored
      This bit need to be set for both RTS/CTS or CTS-to-self protection, if
      CTS-to-self is used, then uCode will  check the RXON_FLG_SELF_CTS_EN
      status. Change the name from TX_CMD_FLG_RTS_CTS_MSK to TX_CMD_FLAG_PROT_REQUIRE_MSK
      to match the behavior of the bit setting.
      
      Also update comments to reflect which hardware uses which of the TX command
      flags.

      iwlwifi: set TX_CMD_FLAG_PROT_REQUIRE_MSK in tx_flag · 062bee44
      Wey-Yi Guy authored
      When building tx command, always set TX_CMD_FLAG_PROT_REQUIRE_MSK
      for 5000 series and up.
      
      Without setting this bit the firmware will not examine the RTS/CTS setting
      and thus not send traffic with the appropriate protection. RTS/CTS is is
      required for HT traffic in a noisy environment where, without this setting,
      connections will stall on some hardware as documented in the patch that
      initially attempted to address this:

          iwlwifi: Fix throughput stall issue in HT mode for 5000
      
          Similar to 6000 and 1000 series, RTS/CTS is the recommended
          protection mechanism for 5000 series in HT mode based on the HW design.
          Using RTS/CTS will better protect the inner exchange from interference,
          especially in highly-congested environment, it also prevent uCode encounter
          TX FIFO underrun and other HT mode related performance issues.
      
      For 3945 and 4965, different flags are used for RTS/CTS or CTS-to-Self
      protection.

      iwlwifi: fix multicast · d1e89f37
      Johannes Berg authored
      commit 3474ad63

          iwlwifi: apply filter flags directly
      
      broke multicast. The reason, it turns out, is that
      the code previously checked if ALLMULTI _changed_,
      which the new code no longer did, and normally it
      _never_ changes. Had somebody changed it manually,
      the code prior to my patch there would have been
      broken already.
      
      The reason is that we always, unconditionally, ask
      the device to pass up all multicast frames, but the
      new code made it depend on ALLMULTI which broke it
      since now we'd pass up multicast frames depending
      on the default filter in the device, which isn't
      necessarily what we want (since we don't program it
      right now).
      
      Fix this by simply not checking allmulti as we have
      allmulti behaviour enabled already anyway.
