hisilicon network subsystem 3 driver (hns3), hisilicon network subsystem driver, networking drivers, the rest · Maintainers:

From: Jiaran Zhang <redacted> 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.
