This series replaces the legacy 32-bit statistics to proper 64-bit ditto,
and implements rx_missed_errors counter on top of that.

The device supports a 16-bit RDRP counter, and a related carry bit and
interrupt, which allows implementation of a robust 64-bit counter.

Esben Haabendal (6):
  net: gianfar: Convert to ndo_get_stats64 interface
  net: gianfar: Extend statistics counters to 64-bit
  net: gianfar: Clear CAR registers
  net: gianfar: Avoid 16 bytes of memset
  net: gianfar: Add definitions for CAR1 and CAM1 register bits
  net: gianfar: Implement rx_missed_errors counter
