====================
ravb Ethernet driver bugfixes

These patches fix bugs found during recent work on the ravb driver.

Patches 1 & 2 affect the R-Car code paths so have been tested on an
R-Car M3N Salvator-XS board - this is the only R-Car board I currently
have access to.

Patches 2, 3 & 4 affect the GbEth code paths so have been tested on
RZ/G2L and RZ/G2UL SMARC EVK boards.

Changes v2->v3:
  * Incorporate feedback from Niklas and add Reviewed-by tag to patch
    "net: ravb: Count packets instead of descriptors in R-Car RX path".
Changes v1->v2:
  * Fixed typos in commit message of patch
    "net: ravb: Allow RX loop to move past DMA mapping errors".
  * Added Sergey's Reviewed-by tags.
  * Expanded Cc list as Patchwork complained that I had missed people.
  * Trimmed the call trace in accordance with the docs [1] in patch
    "net: ravb: Fix GbEth jumbo packet RX checksum handling".
