Subject: [PATCH net v3 0/3] Limit devicetree parameters to hardware capability

This series includes patches that checks the devicetree properties,
the number of MTL queues and FIFO size values, and if these specified
values exceed the value contained in hardware capabilities, limit to
the values from the capabilities. Do nothing if the capabilities don't
have any specified values.

And this sets hardware capability values if FIFO sizes are not specified
and removes redundant lines.

Changes since v2:
- Check if there are hardware capability values
- Add an error message when FIFO size can't be specified
- Change each position of specified values in error messages 

Changes since v1:
- Move the check for FIFO size and MTL queues to initializing phase
- Move zero check lines to initializing phase
- Use hardware capabilities instead of defined values
- Add warning messages if the values exceeds
- Add Fixes: lines

Kunihiko Hayashi (3):
  net: stmmac: Limit the number of MTL queues to hardware capability
  net: stmmac: Limit FIFO size by hardware capability
  net: stmmac: Specify hardware capability value when FIFO size isn't
    specified
