Subject: [PATCH 078/283] net: hns3: add support for imp-handle ras capability
mainline inclusion
from mainline-v5.14-rc1
commit e65e9f5c2e4efc17657d016d767eb7010d9dd598
category: feature
bugzilla: https://gitee.com/src-openeuler/kernel/issues/I8EMUR
CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e65e9f5c2e4efc17657d016d767eb7010d9dd598
----------------------------------------------------------------------
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.
