The command "iw phy ..." only shows hardware capabilities. For DFS
hardware AND software support is needed. In OpenWRT you need hostapd to
support DFS too. The config parameter CONFIG_PACKAGE_ATH_DFS explicitely
activates DFS in hostapd. This parameter is not set by default.
For more information see also the patch with comment in git:
