It basically means the rate control cannot find any rate in
local->hw.wiphy->bands[local->hw.conf.channel->band] that is supported
by the sta in question. Normally this should not happen. I guess the
reason is that the supported rates bits in the sta info are all zero,
which would probably be a bug. I haven't seen this here, but I don't use
the IBSS code either. To further investigate this, you could the
following just before the WARN_ON:
printk(KERN_DEBUG "supported rates bitmask: %08x\n",
sta->supp_rates[sband->band]);
