====================
net: hns3: Additions/optimizations related to HNS3 H/W err handling

This patch set primarily does following addtions and optimizations
related to error handling in HNS3 Ethernet driver:

 1. Name changes for enable and process functions and minor loop
    optimizations. [PATCH 1-6]
 2. Modify query and clearing of RAS errors using new set of commands
    because modules specific commands for clearing RCB PPP PF, SSU are
    obselete. [PATCH 7]
 3. Deletes logging 1-bit errors for RAS in HNS3 driver as these never
    get reported to the driver. [PATCH 8]
 4. Add handling of NIC hw errors reported through MSIx rather than
    PCIe AER channel. [PATCH 9]
 5. Add handling for the HW RAS and MSIx errors in the modules MAC, PPP
    PF, MSIx SRAM, RCB and SSU. [PATCH 10-13]
 6. Add handling of RoCEE RAS errors. [PATCH 14]
