I set SPI clock to 500 000, still have 

at86rf230 spi32765.0: not supported irq 00 received

probably it is an IRQ pin wiring issue, not SPI frequency.

I am trying to do wpan-ping and ping over IPv6, 
ping values seem too high for devices located on the same table
and IPv6 ping has more than double RTT time, maybe it is due to
protocol overhead and so on, but does 45ms for wpan-ping look normal?
