Target Milestone --- 

The NIC RSS symmetric hash is not =
working on the otx2 platform i.e., client to
server and server=C2=A0to client traffic are not hashed=C2=A0to the same co=
re. Below is
code snippet how 4 tuple hashing is enabled on NIC RSS.

As read from a different article, I have tried with symmetric hash_key as 0=
x00,
0x01 instead of 0x6D,0x5A. Even then symmetric=C2=A0hash is not working.

This is critical for my stateful application development. Kindly provide if
there is a way to implement it. Thanks! in advance.

DPDK version used is 20.11.
