* [dpdk-dev] [PATCH] kni: use kni_ethtool_ops only with unknown drivers

From: Igor Ryzhov @ 2018-11-30 19:29 UTC (permalink / raw)
  To: dev

Current implementation of kni_ethtool_ops just uses corresponding
ethtool_ops function of underlying driver for all functions except for
.get_link. This commit sets kni->net_dev->ethtool_ops directly to the
ethtool_ops of the corresponding driver.

For unknown drivers (all but ixgbe and i40e) we still use
kni_ethtool_ops with implemented .get_link function.
