-----------------------+------------------------
 with this configuration which was worker some versions earlier,
 the adhoc-wifi does not come up: ("Cell: Not-Associated")

 {{{
 wireless.radio0=wifi-device
 wireless.radio0.type=mac80211
 wireless.radio0.channel=5
 wireless.radio0.hwmode=11g
 wireless.radio0.htmode=HT20
 wireless.radio0.path=platform/ath9k

 }}}

 however when removing 'mcast_rate' it works.
 with mcast_rate this command from /lib/netifd/wireless/mac80211.sh fails:

 {{{
 iw dev 'wlan0' ibss join 'bb' 2432 HT20 fixed-freq 02:ca:ff:ee:ba:be
 mcast-rate 10
 }}}

 digging through the script there is a (for me) confusing
 call in line 530 of /lib/netifd/wireless/mac80211.sh

 {{{
 hostapd_add_rate mcval "$mcast_rate"
 }}}

 in the wiki: http://wiki.openwrt.org/doc/uci/wireless
 it says "only for adhoc mode". i'am lost...
