Still use memcpy in receiving because we must use buffer fill mode and many packets may share single receive buffer. XXX: Workaround(?) for CXD3222: it fails to DMA for selfid packet according to code placement. I'm not sure about the reason (cache? timing? bug?). Fixed the bug: transmitter sometimes stop and OACTIVE bit of if_fw never be cleared. Fixed the bug: freeing free buffer. Enable ieee1394_drain and ieee1394_watchdog for loss of fragment.
