Linux wireless mac80211 DFS test----Whether support lock-in DFS or not?

Reported by: liuquancheng Owned by: developers
Priority: highest Milestone: Chaos Calmer 15.05
Component: kernel Version: Trunk
Keywords: DFS Cc: nbd@…


Hi all,
We use the SW version and development environment as follows:
Development Environment: OpenWrt trunk version
Linux Wireless: compat-wireless-2014-05-22(ath9k, mac80211, cfg80211, nl80211)
SOC: Atheros AR9344 chip
Wireless Configuration tool: iw-3.15

Currently, our product is testing DFS for CE certification. And our test discovers that Linux wireless mac80211 of OpenWrt trunk version support DFS function. However, For testing, we need to lock-in DFS in order that no allow channel to jump it. Whether the Linux wireless tools(such as, iw) support this function or not?

As is well known, Atheros and Broadcom SDK package have the tool that supports lock-in DFS as follows:

  1. Atheros

For DFS test,
1) radartool usernol 0 (lock-in DFS channel in order to no allow channel to
jump it.)
2) radartool usernol 1 (unlock, DFS channel will jump it when detecting to radar.)

  1. Broadcom

For DFS test,
wl -i wl1 dfs_ism_monitor (set 1=lock-in DFS channel, set 0=unlock DFS channel)

Hoping sincerely that you can give us to a reply.
