Each region has an independently configurable number of maximum snapshots. This information is not reported to userspace, making it not very discoverable. Fix this by adding a new DEVLINK_ATTR_REGION_MAX_SNAPSHOST attribute which is used to report this maximum. Ex: $devlink region pci/0000:af:00.0/nvm-flash: size 10485760 snapshot [] max 1 pci/0000:af:00.0/device-caps: size 4096 snapshot [] max 10 pci/0000:af:00.1/nvm-flash: size 10485760 snapshot [] max 1 pci/0000:af:00.1/device-caps: size 4096 snapshot [] max 10 This information enables users to understand why a new region command may fail due to having too many existing snapshots.
