VoW

  • Transmit buffer enhancements
  • Retry reordering improvements
  • Retry time reduction – aggregate size control
  • Flow control
  • Video stream protection
  • Rate control improvements (RCA)

Transmit Buffer enhancements / 发送缓冲区增强功能

Configuration

  • Compile time This requires the ATH_SUPPORT_VOWEXT configuration macro defined in build system. Please see above file for build configuration file.
  • Runtime configuration If VoW is compiled, it is enabled by default. To further enable or disable, clear the ‘0’ bit in the VowExt configuration.
cfg80211tool wifiX setVowExt 28

Refer to the VSP section for de-queueing VI frames in the presence of video congestion.

Retry reordering improvements / 重试重新排序改进

为了获得更好的性能，驱动程序可以将最多两个聚合排队到硬件。 聚合要么完全成功，要么可能出现一些帧失败。 当框架失败时，它们会添加到待处理帧队列的头部

Configuration

  • Compile-time configuration Enable ATH_SUPPORT_VOWEXT in build/scripts//config.
  • Run-time configuration Check the current configuration of the VoW. If bit 8 is ‘1’ it is enabled already. To disable, place ‘0’ in bit 8; to enable, place ‘1’ in bit 8. For example, if the current configuration returned is 1, using the following command enables this algorithm.
cfg80211tool wifiX setVowExt 0x9

Retry time reduction and aggregate sizing / 减少重试时间和聚合大小

Configuration

  • Compile-time configuration Enable ATH_SUPPORT_VOWEXT in build/scripts//config. for getting this feature enabled.

  • Run-time configuration Check the current configuration of the VoW. If bit-3 is ‘1’ it is enabled already. To disable this place ‘0’ in bit-3, to enable place ‘1’. For example. if the current configuration returned is 1, using the following command would enable this algorithm.
