Duplex mismatch?  Often causes problems where small packets go through
and large ones get silently dropped, or packets only get silently
dropped when the LAN is busy. The usual symptom is excessive
collisions (especially late collisions) logged on the device that's
set half-duplex, and no collisions logged on the device that's set
full duplex.
