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...

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

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