1 do not hide DFS channels in luci web-interface

2 

3 see https://dev.openwrt.org/ticket/14919

4 

5 Channels with the "restricted" flag are not shown by luci.

6 Any channel with one of the following attributes is marked as "restricted" by

7 iwinfo:

8 * NL80211_FREQUENCY_ATTR_PASSIVE_SCAN

9 * NL80211_FREQUENCY_ATTR_NO_IBSS

10 * NL80211_FREQUENCY_ATTR_RADAR

11 

12 The patch removes NL80211_FREQUENCY_ATTR_RADAR from the above list. Thus DFS

13 channels are displayed.

14 

15 Sadly no visual indication is given if the current wireless driver supports DFS.

16 Thus hostapd may refuse to select the configured channel without any further

17 explanation.
