Supports configures the hardware error isolation frequency. 2、Defining the isolation strategy for ACC by uacce sysfs node. If the number of hardware errors in a per hour exceeds the configured value, the device will not be available in user space. The VF device use the PF device isolation strategy. changes v1->v2: - deleted dev_to_uacce api. - add vfs node doc. - move uacce->ref to driver. changes v2->v3: - deleted some redundant code. - use qm state instead of reference count. - add null pointer check. - isolate_strategy_read() instead of a copy. changes v3->v4: - modify a comment changes v4->v5: - use bool instead of atomic. - isolation frequency instead of isolation command.
