*
* ipppp_example_action_cb - handle PPP actions
*
* In order for PPP to function the user must implement this callback function
* used by the PPP module to handle various PPP actions like initialization,
* startup, peer IPv4 address requests, peer authentication, login etc.
*
* Parameters:
* \is
* \i <netif>
* Pointer to Ipcom_netif interface structure define in ipcom_netif.h
* \i <action>
* An action code identifying the basis for calling the callback action routine.
* The following action codes are available:
* \i 'IPPPP_ACTION_INIT'
* The purpose of this callback is to give the PPP system administrator a chance
* to set various PPP, Driver, LCP and/or Authentication initialization
* configuration options for this interface. The callback is only called once
* per interface and immediately after the PPP interface is attached.
* \i 'IPPPP_ACTION_LCP_STARTING'
* Called when LCP is starting. Configure session specific LCP parameters here.
* \i 'IPPPP_ACTION_IPCP_STARTING'
* Called when IPCP is starting.
* This action callback can contain code to override the sysvar configurations
* of local and peer IPv4 address. More precise. the sysvar addresses can be
* overridden by calling ioctl() with the commands SIOCSIFADDR and/or
* SIOCSIFDSTADDR. If the default local IP address is 0 then we want the peer to
* give us an IP address. If the peer address is 0, we refuse to suggest an IP
* address to the peer.
* \i 'IPPPP_ACTION_IPV6CP_STARTING'
* Called when IPV6CP is starting.
* \i 'IPPPP_ACTION_IP_UP'
* Called when IPv4 is up and ready for traffic on this PPP link.
* \i 'IPPPP_ACTION_IP_DOWN'
* Called when IPv4 goes down on this PPP link.
* \i 'IPPPP_ACTION_IPV6_UP'
* Called when IPv6 is up and ready for traffic on this PPP link.
* \i 'IPPPP_ACTION_IPV6_DOWN'
* Called when IPv6 goes down on this PPP link.
* \i 'IPPPP_ACTION_PEER_IDENTIFIER'
* Called when peer sends IPv6 Identifier Configure-Request. See RFC274:p6-8 for
* details. Return -1 if refuse to suggest peer IP identifier, else 0.
* 'data' = pointer to 128-bit IPv6 identifier.
* \i 'IPPPP_ACTION_LOGIN'
* Called when we need to authenticate ourselves (i.e. login) to the peer.
* User code must call ioctl(IP_SIOCXPPPLOGIN) with the interface and link index,
* 'data' as the cookie, user name & password and the function call context when
* ready to login.
* \i <data>
* Action type specific additional data.
* \ie
*
* EXAMPLE
* \cs
* See components/ip_net2-<MAJOR_VER>.<MINOR_VER>/osconfig/vxworks/src/ipnet/ipppp_example.c for
