Subject: [PATCH 1/5] net: hns3: add support for handling all errors through
 MSI-X

Currently, hardware errors can be reported through AER or MSI-X mode.
However, the AER mode is intended to handle only bus errors, but not
hardware errors. On the other hand, virtual machines cannot handle
AER errors. When an AER error is reported, virtual machines will be
suspended. So add support for handling all these hardware errors
through MSI-X mode which depends on a newer version of firmware,
and reserve the handler of the AER mode for compatibility.

Subject: [PATCH 2/5] net: hns3: add the RAS compatibility adaptation solution

To adapt to hardware modification and ensure that the driver is
compatible with the original error handling content, we need to add the
RAS compatibility adaptation solution.

Add a processing branch to the driver during error handling. In the new
processing branch, NIC fault information is integrated by the IMP. An
interaction command is added between the driver and IMP to query
and clear the fault source and interrupt source. The IMP integrates
error information and reports the highest reset level to the driver.

Subject: [PATCH 3/5] net: hns3: add support for imp-handle ras capability

IMP(Intelligent Management Processor) firmware add a new feature to
handle and consolidate RAS information for new devices, NIC driver
only needs to query the reported RAS information. NIC driver adds
support for this feature.

Driver queries device capability to check whether IMP support this
feature, If yes, execute the new RAS processing branch.

In order to add a method to check whether PF supports imp-handle RAS
feature, add dumping this info in debugfs.

Subject: [PATCH 4/5] net: hns3: update error recovery module and type

Update error recovery module and type for RoCE.

The enumeration values of module names and error types are not sorted
in sequence. If use the current printing mode, they cannot be correctly
printed.

Use the index mode, If mod_id and type_id match the enumerated value,
display the corresponding information.

Subject: [PATCH 5/5] net: hns3: add error handling compatibility during
 initialization

During initialization, the driver logs and clears the hw errors that
already occurred. For device supports imp-handle ras capability, it
needs handle different error status, otherwise it may cause wrong reset.

So fix it by adding a new processing branch.
