I am using VxWorks 5.5.1 and MPC 85xx CPU board. I have connected Ixia
to one of the CPU board's interface and configured IPV6 address. When I
send Echo request packet from Ixia to CPU interface, CPU responds with
Echo Reply and ping is successful. But, the Traffic class value is
invariably a constant "0xC0" for all traffic class values that I sent
in Echo Request packets. Could you let me know whether this is a known
issue and what I need to modify in Vxworks to retain the Traffic class
value of the generated packet.
