Currently, enetc_get_ringparam() only provides rx_pending and tx_pending,
but 'ethtool --show-ring' no longer displays these fields. Because the
ringparam retrieval path has moved to the new netlink interface, where
rings_fill_reply() emits the *x_pending only if the *x_max_pending values
are non-zero. So rx_max_pending and tx_max_pending to are added to
enetc_get_ringparam() to fix the issue.
Note that the maximum tx/rx ring size of hardware is 64K, but we haven't
added set_ringparam() to make the ring size configurable. To avoid users
mistakenly believing that the ring size can be increased, so set
the *x_max_pending to priv->*x_bd_count.
