PROTOCOL sending layer 2 packets.. from a os other than linux.. !!!

Dear fundoos,

I am currently using vxworks 6.0. My problem is mmmm, little bit
tricky.. !!! I am trying to send following packet to accesss one of
the network processor oops, i forgot to mention the name it is AXEL-X
fujitsu processor.

The setup ::

(1) X86 machine loaded with vxworks image.
(2) Options enabled :: all network related support. No
INCLUDE_MUX_L2 and INCLUDE_L2CONFIG are enabled.
(3) AXEL_X network processor code is included into my vxworks image.
(4) AXEL-x board is connected through GigaBit ethernet cable to my X86
machine.

The Task -) ::

(1) I have my linux x86 OS from which I am sending a packet using
sockaddr_ll structure ( link layer ) ......yahooo.. my packet is
visible in ethereal. !!! Here below is the dump...

/***************start packet frame *****************/
Frame 127 (60 bytes on wire, 60 bytes captured)

/************end packet... frame.. **************/

Well the above is not a problem LINUX helps me out,, very well...
If you see the above packet it doesn't have IPAddress.. !!!!

coming to vxworks -((((waaaaaaaaaaaaa

(2) I would like to get the same output using
vxworks stack.. i have searched.. searched.. and tired... but unable
to simulate the same environment... and output.. !!!!
I would like to send the following formatted.. data...

---------------------------------------------------------------------------------------------------------------------------------------------------
|DA(6)| SA(6)|Proto Type(2)|msgCode(2)|msgLen(2)|Flag/status(2)|
Identifier(2)|SeqNo.(2)|OptionalData(xx)|
FCS(4) |
----------------------------------------------------------------------------------------------------------------------------------------------------
I am able to send the packet using IP layer ( including IP
address.. )But, unable to send using ONLY MAC ADDRESS...
\
Vxworks 6.x doesn't support sockaddr_ll structure and link layer
packet simulation.. !!!! So, I AM CRYING AND FACING LOT OF
PROBLEMS.. !!!

Tried with the following

sockaddr_dl, sockaddr_in e t c.. But, I am unable to strip and throw
out IPADDRESS from my packet... !!!

This packet will be understandable by AXEL-X Processor.. through
ethernet cable.. ( GBIC ).......

CAN PLEASE PLEASE SOME BODY HELP US REGARDING THIS..

thanks in advance for your help.. what we feel, is there must be some
configuration which is missing so that i can send packets using mac
address also.. !!!

CHEERS AND WAITING -)))

With love skywalker. !!!

Well, it is not an IP packet. It is a vendor-specific protocol packet!
