After a hardware reset, the key memory content is not cleared. This means that
all keys are still valid. The state between the hardware CAM and the software driver
shadow is inconsistent. For this reason, the software API stcam_create or
stcam_delete_all function must be called prior to allowing any API operations to be
performed in the CAM. stcam_create or stcam_delete_all ensures that the hardware and
software are synchronized. In LPM Mode, you must call the corresponding
lpm_create or lpm_delete_all functions
instead.
