In our project, we are not planning to change the base OS
(Vxworks 5.5), we are just planning to take network stack. Thats the
reason, why I am evaluating Vxworks 5.5 OS and Vxworks 6.7 network
I am not able to compile it successfully (with Vxworks OS 5.5 and
IPNET-IPCOM-IPTCP code from 6.7 combination). I am getting lot of
errors in ipcom_drv_eth. Did you faced these kind of issues? or is
there any documentation that I have to read to overcome all this?
