This parameter overrides the default universally administered address of the adapter card, and must be unique among all of the networked adapter addresses. For Token Ring adapters, this parameter must be within the hex range 400000000000 through 7FFFFFFFFFFF. For Ethernet adapters, this parameter is entered in canonical format, such as 020000000000. The corresponding group address bit must not be set." ; ; MAC driver tuning parameters ; [MaxTransmits] display = "Maximum number of queued transmits" type = Decimal Default = "31" Range = 1 - 512 Optional = Yes Editable = Yes Virtual = No Help = "This parameter specifies the maximum number of transmit queue entries, and may be set to a value from 1 to 512. The network adapter driver allocates approximately 400 bytes for each transmit queue entry. The value of this parameter should be high enough to accommodate the sum of all Maximum Number of Queued Transmits parameter values for all protocol drivers using the adapter concurrently."

It serves as an upper limit, since the actual frame size maximum may be less. The maximum transmit frame size supported by the MAC driver is the smallest of this parameter, the Total Receive Buffer Area, or the physical frame size capacity of the network being used. Do not count the 4 bytes of CRC defined for a frame when setting this value."

The Total Receive Buffer Area for the network adapter is calculated from the product of this parameter and the Size of Adapter Driver Receive Buffer parameter. The maximum receive frame size allowed by the network is 1518 bytes for Ethernet, 4504 bytes for 4 Mbps Token Ring, and 18004 bytes for 16 Mbps Token Ring. The maximum frame size supported by the device driver is the smallest of the Total Receive Buffer Area, the network maximum receive frame size, or the Maximum Transmit Frame Size parameter."

The allowable range covers both Token Ring and Ethernet adapters, but specific ranges are enforced by the device driver for the particular network type as follows: Ethernet 64 to 2048 bytes, Token Ring 96 to 18000 bytes. If this parameter is not specified, or is set to a value outside of the allowable range for the network type, a common default will be used."

A YES value indicates that transmit end of frame interrupt will be recognized by the interrupt handler. A NO value indicates that the transmit end of frame should not be recognized by the interrupt handler.

If this parameter is set to NO, then frames transmitted by this station that would also be received by it will not be copied, and the frames must be looped back by the protocol stack instead. If this parameter is a YES, loopback will be handled by the adapter. If not specified, loopback will be set to YES by the device driver, except if using a 16-bit adapter or a 16-bit bus slot, then loopback is set to NO (this exception does not apply for 4 Mbps Token Ring operation)."

Setting a value of YES will enable this channel, and the Maximum High-Priority Transmit Access Priority and the High-Priority Transmit Channel Threshold parameters will be used to configure its operation.
