From: Huazhong Tan Date: Wed, 20 Nov 2019 02:07:15 +0000 (+0800) Subject: net: hns3: fix a wrong reset interrupt status mask X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=74e78d6bae1904e87469da5ed87e9f6bd1131f46;p=uclinux-h8%2Flinux.git net: hns3: fix a wrong reset interrupt status mask According to hardware user manual, bits5~7 in register HCLGE_MISC_VECTOR_INT_STS means reset interrupts status, but HCLGE_RESET_INT_M is defined as bits0~2 now. So it will make hclge_reset_err_handle() read the wrong reset interrupt status. This patch fixes this wrong bit mask.
