* Note:
* Atheros AR81xx does not support descriptor based DMA on Rx
* instead it just prepends a Rx status structure prior to a
* received frame which also resides on the same Rx buffer.
* This means driver should copy an entire frame from the
* buffer to new mbuf chain which in turn greatly increases CPU
* cycles and effectively nullify the advantage of DMA
* operation of controller. So you should have fast CPU to cope
* with the copy operation. Implementing flow-controls may help
* a lot to minimize Rx FIFO overflows but it's not available
* yet on FreeBSD and hardware doesn't seem to support
* fine-grained Tx/Rx flow controls.
