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.

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
