For performance monitoring the receive buffer provides the capability to monitor the
receive buffer utilization and to generate interrupts when certain fill thresholds have been
reached.

The internal transmit buffer with a total size of 32 kByte stores protocol data before it is
processed by the protocol machine. The transmit buffer is essential to ensure that
enough data is available during transmission, since PCI latency and usage of multiple
