Merge branch 'macb-ethtool-ringparam'
Zach Brown says: ==================== macb: 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. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
