- This can work around link stability and data corruption issues on gigabit
- links which can occur in slave mode on certain PHYs, e.g. on the

- Please note that two directly connected devices (i.e. via crossover cable)

- master mode. Multiple devices forcing master mode when connected by a
- network switch do not pose a problem as the switch configures its affected

- This option only affects gigabit links. If you must establish a direct
- connection between two devices which both force master mode, try forcing
- the link speed to 100MBit/s.
