by Hi,
I would really appreciate if you can help me with the following :
I have written a pseudo driver (module) in solaris (2.5) which will sit
below
IP layer and above the Device Driver (which is also a streams driver,
ATM NIC Driver). I have been able to load it as a streams module by
calling "modload mydriver" ( I had copied mydriver in the /kernel/drv)
directory.
I have to do the following which I am not able to do, please help me
out :
1. Open a device which will cause an open of "mydriver" ? My driver
supports clone opens, but I don't know how to open this driver from the
user application. I tried creating a device in the /dev directory but
the open system call [open("/dev/mydriver",O_RDWR)] fails with "no such
device". ls -l of mydriver in the /dev directory looked as follows :
/dev> pwd
/dev
/dev> ls -l mydriver
lrwxrwxrwx 1 root other 29 Feb 15 22:44 /dev/mydriver ->
2. I want to plumb "mydriver" below IP. How do I do it ? My requirement
is that multiple streams of "mydriver" each with a different
configuration should be attached directly below IP (each will be
assigned a different IP address). How do I use "ifconfig" to assign IP
address to such a device , what interface address do I specify ?
-------
| IP |
-------
|
-----------
|mydriver |
------------
|
------------------
| ATM NIC Driver |
------------------
3. Is it possible to insert another module say "mydriver1" between IP
and mydriver ? How ?
Thanks a lot in advance.
Regards,
Balaji
