Hi,
I’m building intermediate driver which is located below IP.
uname -a is:
QNX6.1.0 2002/08/23-19:38:50edt x86pc x86
In my system the user is loaded ppp connection from time to time.
Each time the user is doing that I need to catch the allocated ppp IP
address and update with it my driver.

- Any idea how do I do it?
- how do I do the same for Ethernet? (or is it the same way?)
Watch out the npkt with “_NPKT_MSG” flag set, there will be a
“_IO_NET_MSG_ADDR_ADD” as well as “_IO_NET_MSG_ADDR_DEL” go
though you (since you are below IP, these packets probably
comming in from your rx_up() function), these “message packet”
is meant to told you and IP address is set/deleted.

Actually i think the IO_NET_MSG_ADDR_ADD/DEL come in the rx_down functions
since they are generated by the IP layer.

Well the winner is rx_down.
After tracing with gdb on the io-net I can see that when a user does
ifconfig command, which changes the current IP address the rx_down function
is immediately been called with the mentioned flags.
Thanks people!

mmmmm…
Where does the IO_NET_MSG_ADDR_ADD/DEL should be located on ?
How can I fetch it?
