    rt2x00: Hardcode TX ack timeout and consume time · 4789666e
    Ivo van Doorn authored
    The calculated values for the ACK timeout and ACK
    consume time are different then the values as
    used by the Legacy drivers.
    
    After testing from James Ledwith it appeared that
    the calculated values caused a high amount of TX
    failures, and the values from the Legacy drivers
    were the most optimal to prevent TX failure due to
    excessive retries.
    
    The symptoms of this problem:
     - Rate control module always falls back to 1Mbs
     - Low throughput when bitrate was fixed
    
    Possible side-effects (not confirmed but highly likely)
     - Problems with DHCP
     - Broken connections due to lack of probe response
    
    This should fix at least:
    Kernel bugzilla reports: [13362], [13009], [9273]
    Fedora bugzilla reports: [443203]
    but possible some additional bugs as well.
