This patchset enables DFS channels in mesh mode along with
CAC and channel switch.
It's been verified that works for non-dfs channels, dfs channels,
w/wo encryption (none and SAE), radar detection, channel switch,
and mesh re-association after channel switch.
Only left area to cover is in the case when multiple mesh points
detect radar at the same time, but they select different channels.
To cover the case I think we need a private patch for it,
because current 802.11s standard does not address it how to handle.

Thanks !
Though I tried your patch with my test, it looks not work for me.
The wlan0 could receieve DFS-CAC-START but wlan1 not.

My Linux kernel is letest wireless-testing commit
a07a0eb946c5bf461258fcccd374dc61c89566d5 "Add localversion to identify
builds
from this tree"
And I found some compiler warnings and a memory leak in your patches.
I will send some patches for these and my test case.
