2017-11-02net: hns3: hns3:fix a bug about statistic counter in reset processqumingguang1-0/+7
All member of Struct hdev->hw_stats is initialized to 0 as hdev is allocated by devm_kzalloc. But in reset process, hdev will not be allocated again, so need clear hdev->hw_stats in reset process, otherwise the statistic will be wrong after reset. This patch set all of the statistic counters to zero after reset.

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.
