Subject: [PATCH 0/2] Add ethtool get_ringparam and set_ringparam to cadence

There are use cases like RT that would benefit from being able to tune the
macb rx/tx ring sizes. The ethtool set_ringparam function is the standard way
of doing so.

The first patch changes the hardcoded tx/rx ring sizes to variables that are
set to a hardcoded default.

The second patch implements the get_ringparam and set_ringparam fucntions.

Zach Brown (2):
  net: macb: Use variables with defaults for tx/rx ring sizes instead of
    hardcoded values
  net: macb: Add ethtool get_ringparam and set_ringparam functionality
