    ath5k: add antenna statistics and debugfs file for antenna settings · 604eeadd
    Bruno Randolf authored
    keep statistics about which antenna was used for TX and RX. this is used only
    for debugging right now, but might have other applications later.
    
    add a new file 'antenna' in debugfs (/sys/kernel/debug/ath5k/phy0/antenna) to show
    antenna use statistics and antenna diversity related register values. it can
    also be used to set the antenna mode until we have proper support for that in
    iw:
      - echo diversity > antenna: use default antenna mode (RX and TX diversity)
      - echo fixed-a > antenna: use fixed antenna A for RX and TX
      - echo fixed-b > antenna: use fixed antenna B for RX and TX
      - echo clear > antenna: reset antenna statistics
