Merge branch 'hns3-next'

Huazhong Tan says:

====================
code optimizations & bugfixes for HNS3 driver

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

[patch 1/12] fixes a compile warning reported by kbuild test robot.

[patch 2/12] fixes HNS3_RXD_GRO_SIZE_M macro definition error.

[patch 3/12] adds a debugfs command to dump firmware information.

[patch 4/12 - 10/12] adds some code optimizaions and cleanups for
reset and driver unloading.

[patch 11/12 - 12/12] adds two bugfixes.
