Notes

  1. ^ abcd 'N/A' means firmware is stored in device at all times
  2. ^ abcdef The card doesn't have a host CPU and so it doesn't require a firmware source
  3. ^ The proprietary HAL can be replaced by a port of the OpenHAL (from the BSD ath driver) to Linux
  4. ^ See openfwwf project for open source firmware. This firmware lacks support for QoS and hardware cryptography.
