[PATCH V4 net-next 7/8] net: hns3: Add Ethtool support to HNS3 driver

From: Salil Mehta
Date: Sat Jul 22 2017 - 18:12:25 EST


This patch adds the support of the Ethtool interface to
the HNS3 Ethernet driver. Various commands to read the
statistics, configure the offloading, loopback selftest etc.
are supported.
