help
This option enables the deprecated WDS support, the newer
mac80211-based 4-addr AP/client support supersedes it with
a much better feature set (HT, VHT, ...)
We plan to remove this option and code, so if you find
that you have to enable it, please let us know on the
linux-wireless@vger.kernel.org mailing list, so we can
help you migrate to 4-addr AP/client (or, if it's really
necessary, give up on our plan of removing it).
