The current IEEE802.15.4 stack assumes that a radio will never deliver
packets with a bad CRC into the stack, as required by the standard.
at86rf230 driven radios violates this assumption because of another
incompatibility: devices are required to send ACKs if requested by a
sender, but RF2xx will only send ACKs from a special receive mode that
is currently not used by the driver.
Enable this receive mode to fix both bugs. Frames with bad CRCs will not
be received at all, and ACKs will be sent if so requested.
