Common IEEE 802.11 properties
This provides documentation of common properties that are valid for all wireless
Optional properties:
- ieee80211-freq-limit : list of supported frequency ranges in KHz. This can be
used for devices that in a given config support less channels than
normally. It may happen chipset supports a wide wireless band but it is
limited to some part of it due to used antennas or power amplifier.
An example case for this can be tri-band wireless router with two
identical chipsets used for two different 5 GHz subbands. Using them
incorrectly could not work or decrease performance noticeably.
