Don't worry, you were very clear in this e-mail.

Thanks for taking the time.  As stated, I think it would be best to have
these or some other some brief comments about the different flow types
in the source code (and especially the documentation) of ethtool.

Based on your explanation, I agree that indeed those are all different
flow types that occur in real-life on PGW/UPF and other 3GPP network
elements/functions.  I can also very well imagine that there are use
cases to steer all of those separately, including the EH and UL/DL types
you mentioned.

So I'm supporing your patch with all its many different flow types for RSS.

Thanks,
	Harald
