File PnP.h
|
|
|
|
Declarations required to make the interface between the IPX stack and the IPX
|
|
user-mode router components software PnP enabled.
|
|
|
|
This file will plug into the NT 4.0 version adptif and provide the
|
|
following PnP capabilities:
|
|
|
|
1. Notify IPX router when new net cards are added (via PCMIA, bindings, etc.)
|
|
2. Notify IPX router when the internal network number changes.
|
|
3. Notify IPX router when changes to existing net cards occur:
|
|
- Changes to network number associated with a given adapter
|
|
- Changes to the frame type of a given adapter
|
|
|
|
|
|
Strategy for notifying IPX router components of adapter changes
|
|
===============================================================
|
|
1. In NT 4.0, the stack would complete the MIPX_GETNEWNICINFO IOCTL whenever
|
|
a wan link went up or down, whenever certain lan configuration changed,
|
|
and in some other instances. For PnP, we will modify the IPX stack to
|
|
complete this IOCTL whenever the internal net number changes and
|
|
whenever an adapter-related PnP event occurs.
|
|
|
|
2. As part of processing the adapter configuration changes returned from the
|
|
completion of the MIPX_GETNEWNICINFO IOCTL, adptif should also send the
|
|
MIPX_CONFIG ioctl to get the internal network number and verify
|
|
that it hasn't changed. If it has changed, all ipx router components
|
|
should be notified.
|
|
|
|
3. Each router component (rtrmgr, rip, sap) is a client to adptif.dll and will
|
|
will therefore be notified about each adapter configuration change. These
|
|
components will have to be modified to deal with these changes individually.
|
|
For example, sap will have to update its service table to reflect new network
|
|
numbers and broadcast these changes to the network. The router manager will
|
|
have to instruct the fowarder to update its route table, etc.
