[net PATCH v2 0/2] Fix maximum TX/RX frame sizes in ravb driver

Posted by Paul Barker 1 year, 3 months ago

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.

For the R-Car AVB IP, the maximum TX frame size should be 2047 (not
2048), but additional work will be required to validate that change so
it is not included in this series.

Changes v1->v2:
  * Rebase on net tree as these are both bugfixes.
  * Pick up Reveiwed-by tags.
