In Auto-negotiation mode, no default value. In Forced mode, default
value depends on your setting.
Flow Control:
There are two modes to choose in flow control, including Symmetric
and Asymmetric. If flow control is set Symmetric, both parties can
send PAUSE frame to the transmitting device(s) if the receiving port is
too busy to handle. When it is set Asymmetric, this will let the recei-
ving port care the PAUSE frame from transmitting device(s), but it
doesn't send PAUSE frame. This is one-way flow control.
Default: Symmetric.
Maximum Frame:
This module offer 1518~9600 (Bytes) length to make the long
packet.
Excessive Collision Mode:
There are two modes to choose when excessive collision happen in
half-duplex condition as below:
Discard: The "Discard" mode determines whether the MAC drop fra-
mes after an excessive collision has occurred. If set, a frame is drop-
ped after excessive collisions. This is IEEE Std 802.3 half-duplex flow
control operation.
Restart: The "Restart" mode determines whether the MAC retransmits
frames after an excessive collision has occurred. If set, a frame is not
dropped after excessive collisions, but the backoff sequence is restar-
ted. This is a violation of IEEE Std 802.3, but is useful in non-dropping
half-duplex flow control operation.
