The dynamic device personalization (DDP) file download onto the device can fail, and when this happens the driver has to transition to "safe mode" where only basic functionality is possible. The device though doesn't understand safe mode, and so the opcodes to discover device/function capabilities (0x000A and 0x000B) return all the capabilities of the device, which includes capabilities that the driver cannot support when in safe mode. The initialization flows in the driver are based on the capabilities information (obtained by the driver with the above mentioned opcodes). To reuse the same initialization flows in safe mode, it becomes necessary for the driver to override the currently stored capabilities information with safe mode capabilities. This is done by a new function introduced in this patch - ice_set_safe_mode_caps.
