Subject: [PATCH 142/189] net/hns3: fix clearing hardware MAC statistics

In the situation that the driver hns3 exits abnormally during packets
sending and receiving, the hardware statistics are not cleared when the
driver hns3 is reloaded. It need to be cleared during driver hns3
initialization that hardware MAC statistics.
