* The following two parameters set the maximum number of
|
|
* transmitting and receiving slots between the driver and
|
|
* an adapter. It must be defined within the range of [8, 32].
|
|
* More slots requires more memory for each adapter.

* To change them for each adpater, mtrconfig(1M) should be used

* Broadcast bits for route discovery EXPLORER frames:
|
|
*
|
|
* 0x8000 - use All-route Broadcast, nonbroadcast return.
|
|
* 0xc000 - use Single-route Broadcast, All-Route broadcast return.

|
* 0xe000 - use Single-route Broadcast, nonbroadcast return.

* customized mtu:
|
|
*
|
|
* 4472 - max MTU for 4 Mbit ring.
|
|
* 17800 - max MTU for 16 Mbit ring.
|
|
*
|
|
* However, many bridges limit the max frame size to 4472, so the
|
|
* default MTU used is 4472. If there are no bridges in the tokenring
|
|
* network topology, mtr_mtu can be increased, subject to the limits
|
|
* specified above, for a higher throughput.

|
*
|
|
* When receiving, the board accepts all broadcast addresses
|
|
* specified by the ANSI 802.5 spec.
|
|
*
|
|
* But some PC/bridge implementations honor only 0xC000FFFFFFFF,
|
|
* so when transmitting the destination broadcast address will
|
|
* be set as specified by mtr_batype below.
|
|
*
|
|
* type 1 -> use 0xc000ffffffff
