Subject: [PATCH V7 net-next 0/4] Support some features for the HNS3 ethernet driver

Currently, the hns3 driver does not have the trace
of the command queue. As a result, it is difficult to
locate the communication between the driver and firmware.
Therefore, the trace function of the command queue is
added in this patch set to facilitate the locating of
communication problems between the driver and firmware.

If a RAS occurs, the driver will automatically reset to attempt
to recover the RAS. Therefore, to locate the cause of the RAS,
it is necessary to save the values of some RAS-related registers
before the reset. So we added a patch in this patch set to
print these information.
