//** LLIPIF.H - Lower layer IP interface definitions.
|
||
|
|
//
|
||
|
|
// This file contains the definitions defining the interface between IP
|
||
|
|
// and a lower layer, such as ARP or SLIP.
|
||
|
|
|
||
|
|
/*
|
||
|
|
This file defines a new and improved IP to ARP Module interface definition and will replace llipif.h.
|
||
|
|
This will also retire the IOCTL method of registering ARP interfaces. The main points are:
|
||
|
|
|
||
|
|
- It simplifies setup such that the ARP Modules do not have their own bindings in addition to IP bindings.
|
||
|
|
- Lets ARP Modules expose multiple IP interfaces per binding.
|
||
|
|
- Adds version numbering for future compatibility.
|
||
|
|
- Adds Multi-send capability to ARP
|
||
|
|
- Lets ARP indicate a packet up in NDIS 4.0 style and IP hang onto the packet and avoid copying.
|
||
|
|
|
||
|
|
The flow today is:
|
||
|
|
------------------
|
||
|
|
|
||
|
|
ARP gets a bind indication from NDIS.
|
||
|
|
ARP calls IPAddInterface
|
||
|
|
IP calls ARP_REGISTER
|
||
|
|
|
||
|
|
The proposed flow is:
|
||
|
|
---------------------
|
||
|
|
|
||
|
|
ARP Registers itself with IP via IPRegisterARP(). The ARP is identified by its Name which is case insensitive.
|
||
|
|
|
||
|
|
IP gets a bind indication from NDIS. It opens the config section and read the ARP name. Empty name implies
|
||
|
|
built in ARP as usual.
|
||
|
|
IP calls ARP's bind handler passing in the config handle.
|
||
|
|
ARP then opens the adapter and adds one or more IP interfaces via IP_ADD_INTERFACE. For each of up-call ARP
|
||
|
|
passes in the config-handle for that interface to IP. In most cases it is the same handle which IP passed
|
||
|
|
to ARP. In case of multiple IP interfaces per adapter it is not.
|
||
|
|
Calls IPBindComplete() when done.
