  TXRX_CSR5 stores allowable ACK rates instead of basic rates, so rename
  rt2661_set_basicrates() to rt2661_set_ackrates().  Also turn on 6Mbits/s,
  12Mbits/s and 24Mbits/s in ACK rates, if we are not forced to be in 11b
  mode and to start/join an ERP BSS.  Now rt2661 part will send ACK at
  24Mbits/s instead of 6Mbits/s, if the data to be acknowledged are sent at
  rate above/equal 24Mbits/s, which is standard conforming and improves
  performance a bit.
  # This problem is identified by running following command on any NIC
  # that can capture control frames and is aware of ERP:
  #   tcpdump -ni iface -y ieee802_11_radio not wlan type mgt
  # Pay attention to the rate, at which ACK gets sent ;]
