The packet accelerator low level driver module will make call backs to the module user when it is about to modify from one of the two tables provided by the module user. If the module user is operating in a multi-core environment with a single set of tables shared by all the cores, then this function is used to tell the application to apply a cross core semaphore.

When table modification is done the module will again make a call back to the module user to inform it to release the semaphore.
