If anyone has any objections, please let me know. ------------------ From: Wei Fang [ Upstream commit 70b439bf06f6a12e491f827fa81a9887a11501f9 ] 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.
