Make sure all statistics the d80211 stack requires.
Some of this requires values to be read during
interrupt process (add a new function to handle this).
And other fields can be read from the registers at
request time.
Note that rt61pci and rt73usb had an invalid registername
the legacy drivers are suggesting the CRC_ERROR count is
actually the FCS_ERROR count.
