[dpdk-dev] [PATCH] net/hns3: support RAS process in Kunpeng 930

[dpdk-dev] [PATCH] net/hns3: support RAS process in Kunpeng 930

[Min Hu (Connor)]

From: Hongbo Zheng <zhenghongbo3@huawei.com>

Kunpeng 930 uses a new RAS exception reporting solution.
The reset type and exception status are reported through
firmware. The driver modifies the corresponding code to
adapt to the new solution.
