====================
net: hns3: some code optimizations & cleanups & bugfixes

This patch-set includes code optimizations, cleanups and bugfixes for
the HNS3 ethernet controller driver.

[patch 1/12 - 6/12] adds some code optimizations and bugfixes about RAS
and MSI-X HW error.

[patch 7/12] fixes a loading issue.

[patch 8/12 - 11/12] adds some bugfixes.

[patch 12/12] adds some cleanups, which does not change the logic of code.
====================
