It looks like the key missing part was the use of P2P_DEV_FORCE_FREQ
flag which was already missing before this patch. I fixed and cleaned up
the previous implementation and then applied a rebased version of this
patch 2/3 with a somewhat more accurate commit log (and with the
wpa_msg() call moved to the caller to avoid confusing debug log
entries).
