  Log:
  o track API change for HAL v0.9.6.1
  o fix race condition when processing rx descriptors: because we use
    a self-linked descriptor at the end of the rx descriptor list to
    avoid rx overruns (which can easily happen for 5212 parts that enable
    PHY errors) we must carefully check that a descriptor is "done" by
    looking ahead to the next descriptor before believing the done bit
    in the current descriptor (this is all handled in the HAL since the
    rx descriptor format is chip-specific so we need to pass in two
    additional parameters--the physical address of the current descriptor
    and the virtual address of the next descriptor in the list)
  o check copyout return status for SIOCGATHSTATS ioctl
