Note – If a parameter’s initial setting is 0, it cannot be changed. If you try to change
it, it will revert back to 0.
If all these parameters are set to 1, autonegotiation will use the highest speed
possible. If all these parameters are set to 0, you will receive the following error
message:
Flow Control Parameters
The ce device is capable of sourcing (transmitting) and terminating (receiving)
pause frames conforming to the IEEE 802.3x Frame Based Link Level Flow Control
Protocol. In response to received flowcontrol frames, the ce device can slow down
itstransmit rate. On the other hand, the ce device is capable of sourcing flow control
frames, requesting the link partner to slow down, provided that the link partner
supports this feature. By default, the driver advertises both transmit and receive
pause capability during autonegotiation.
