      ath10k: replenish htc tx credits always · 5d5c8ec9
      Michal Kazior authored
      
      
      There's always at most 2 credits and it makes
      little sense to set the
      ATH10K_HTC_FLAG_NEED_CREDIT_UPDATE flag
      conditionally.
      
      This seems to fix some random issues with tx
      credit starvation on WLAN.RM.2.0-00073 I've been
      seeing. Note: this isn't related to wmi mgmt tx.

      ath10k: fix insufficient tracing buffer size · f42f8eb2
      Michal Kazior authored
      Some trace messages were truncated and a kernel
      splat could be seen in the log:

      ath10k: disable burst mode · 24ab13ef
      Janusz Dziedzic authored
      
      
      Firmwares that indicate BURST_SERVICE as enabled
      could overwrite some wmm parameters (eg. txop).
      This could lead IOT and balancing issues.
      Hence disable this by default.
