[PATCH V7 net-next 3/4] net: hns3: dump more reg info based on ras mod
From: Jijie Shao
Date: Wed Apr 10 2024 - 09:00:08 EST
From: Peiyang Wang <wangpeiyang1@xxxxxxxxxx>
When the driver received an interrupte for hardware error,
it will try to restore by resetting. But the hardware registers
will also be reset at this case, which make it hard to analysis
why the hardware error occurs.
This patch dumps these registers before resetting to help
analyze the hardware error occurs.
