Subject: [PATCH AUTOSEL for 4.14 090/135] net: hns3: fix the TX/RX
 ring.queue_index in hns3_ring_get_cfg

From: Lipeng <lipeng321@...wei.com>

[ Upstream commit 66b447301ac710ee237dba8b653244018fbb6168 ]

The interface hns3_ring_get_cfg only update TX ring queue_index,
but do not update RX ring queue_index. This patch fixes it.

Fixes: 76ad4f0 (net: hns3: Add support of HNS3 Ethernet Driver for hip08 SoC)
