- * FIXME: large timeout, ethernet pause frames...
- *
- * Use a large timeout to work-around the fact that
- * flow-control may throttle outgoing control packets
- * due to its use of ethernet pause frames.
- *
- * This will be fixed when host-based flow control is implemented,
- * along with larger incoming send buffers using the on-board SRAM.
