- * Special Interrupt handler
- *
- * The following abstract should show how this module is included
- * in the driver path:
- *
- * In the ISR of the driver the bits for frame transmission complete and
- * for receive complete are checked and handled by the driver itself.
- * The bits of the slow path mask are checked after that and then the
- * entry into the so-called "slow path" is prepared. It is an implementors
- * decision whether this is executed directly or just scheduled by
- * disabling the mask. In the interrupt service routine some events may be
- * generated, so it would be a good idea to call the EventDispatcher
- * right after this ISR.
- *
- * The Interrupt source register of the adapter is NOT read by this module.
- * SO if the drivers implementor needs a while loop around the
- * slow data paths interrupt bits, he needs to call the SkGeSirqIsr() for
- * each loop entered.
- *
- * However, the MAC Interrupt status registers are read in a while loop.
