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 flow control frames, the

ce

device can slow down

its transmit 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.

adv-100hdx-cap

Local interface capability advertised by the hardware
0 = Not 100 Mbit/sec half-duplex capable
1 = 100 Mbit/sec half-duplex capable (default)

adv-10fdx-cap

Local interface capability advertised by the hardware
0 = Not 10 Mbit/sec full-duplex capable
1 = 10 Mbit/sec full-duplex capable (default)

adv-10hdx-cap

Local interface capability advertised by the hardware
0 = Not 10 Mbit/sec half-duplex capable
1 = 10 Mbit/sec half-duplex capable (default)

NOTICE: Last setting will leave ce1 with no link capabilities.

WARNING: ce1: Restoring previous setting.
