What is fethPortAlignmentErrors?

Counts legal-length frames on this port that failed both the FCS check and had a framing (non-byte-aligned) error without an accompanying collision; as with the 10Mbps equivalent, a climbing count usually points to a physical-layer or wiring problem on the segment feeding this port.
