devlink: expand the devlink-info documentation We are having multiple review cycles with all vendors trying to implement devlink-info. Let's expand the documentation with more information about what's implemented and motivation behind this interface in an attempt to make the implementations easier. Describe what each info section is supposed to contain, and make some references to other HW interfaces (PCI caps). Document how firmware management is expected to look, to make it clear how devlink-info and devlink-flash work in concert. Name some future work. v2: - improve wording v3: - improve wording Signed-off-by: Jakub Kicinski <kuba@kernel.org> Reviewed-by: Randy Dunlap <rdunlap@infradead.org> Signed-off-by: David S.

devlink: Add new "enable_eth" generic device param Add new device generic parameter to enable/disable creation of Ethernet auxiliary device and associated device functionality in the devlink instance. User who prefers to disable such functionality can disable it using below example. $ devlink dev param set pci/0000:06:00.0 \ name enable_eth value false cmode driverinit $ devlink dev reload pci/0000:06:00.0 At this point devlink instance do not create auxiliary device for the Ethernet functionality.

devlink: Add enable_remote_dev_reset generic parameter The enable_remote_dev_reset devlink param flags that the host admin allows device resets that can be initiated by other hosts. This parameter is useful for setups where a device is shared by different hosts, such as multi-host setup. Once the user set this parameter to false, the driver should NACK any attempt to reset the device while the driver is loaded.
