Interrupt Entry Point
The information in the interrupt queue is read and a message containing that information
is sent to the user.
In case of a received frame the written receive descriptors are linked to a message and
sent to the user. The next available descriptor in the list is linked to the memory
structures. An equivalent number of new receive descriptors is allocated and linked to
the end of the receive descriptor queue.
In case of a transmit acknowledge interrupt the used transmit descriptors are released
to the descriptor pool.
