Subject: [PATCH net-next 0/3] net: xilinx: axienet: Add statistics support

Add support for hardware statistics counters (if they are enabled) in
the AXI Ethernet driver. Unfortunately, the implementation is
complicated a bit since the hardware might only support 32-bit counters.
In the future, we could add a simpler alternate implementation for
64-bit counters enabled with a device-tree property, but for now I've
gone with a unified implementation.

  net: xilinx: axienet: Report RxRject as rx_dropped
