Why is the aFrameCheckSequenceErrors counter of the Triple Speed Ethernet (TSE) IP core incremented when alignment errors occur?

Description
Due to a bug in the Triple Speed Ethernet (TSE) IP core, starting in IP version 13.0, the aFrameCheckSequenceErrors counter may be incremented when alignment errors occur. A frame with alignment errors should be recognized as an invalid frame, hence aFrameCheckSequenceErrors should not be incremented.
Resolution
This bug is fixed in IP core version 14.1 and later.
