Subject: [net-next PATCH 0/2] Fix maximum TX/RX frame sizes in ravb driver

These patches fix a couple of bugs in the maximum supported TX/RX frame sizes
in the ravb driver.

  * For the GbEth IP, we were advertising a maximum TX frame size/MTU that was
    larger that the maximum the hardware can transmit.

  * For the R-Car AVB IP, we were unnecessarily setting the maximum RX frame
    size/MRU based on the MTU, which by default is smaller than the maximum the
    hardware can receive.

Paul Barker (2):
  net: ravb: Fix maximum MTU for GbEth devices
  net: ravb: Set R-Car RX frame size limit correctly
