[PATCH net] net: enetc: fix the output issue of 'ethtool --show-ring'

[Wei Fang]

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 rx_pending/tx_pending only if the corresponding
rx_max_pending/tx_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.

Fixes: e4a1717b677c ("ethtool: provide ring sizes with RINGS_GET request")
