From 7036d26f328f12a323069eb16d965055b4cb3795 Mon Sep 17 00:00:00 2001 From: Lipeng Date: Tue, 24 Oct 2017 21:02:09 +0800 Subject: net: hns3: fix the bug of hns3_set_txbd_baseinfo The SC bits of TX BD mean switch control. For this area, value 0 indicates no switch control, the packet is routed according to the forwarding table. Value 1 indicates that the packet is transmitted to the network bypassing the forwarding table. As HNS3 driver need support VF later, VF conmunicate with its own PF need forwarding table. This patch sets SC bits of TX BD 0 and use forwarding table. Fixes: 76ad4f0 (net: hns3: Add support of HNS3 Ethernet Driver for hip08 SoC) Signed-off-by: Lipeng Signed-off-by: David S.
