From 5f8845f4ba8f8059710bdcc39306f91743532c69 Mon Sep 17 00:00:00 2001 From: Hongbo Zheng Date: Thu, 4 Mar 2021 15:44:53 +0800 Subject: [PATCH] net/hns3: process MAC interrupt TNL is the abbreviation of tunnel, which means port here. MAC TNL interrupt indicates the MAC status report of the network port, which will be generated when the MAC status changes. This patch enables MAC TNL interrupt reporting, and queries and prints the corresponding MAC status when the interrupt is received, then clear the MAC interrupt status. Because this interrupt uses the same interrupt as RAS, the interrupt log is adjusted.
