IIRC, that's what I found after divig the code. It's an issue
reported/fixed by Finn. I also don't have the nic for testing.
[Finn] Yes, this was needed to make our test setup using an XL710 work,
with the rte_flow implementation.
It's a while ago so I don't exactly remember how we ended up with this
solution. However, we are definitely not
Intel XL710 experts, so there might be other ways to achieve the rte_flow
functionality.
This issue, and problem raised about the overall change in configuration
impact on NICs using this setting (Napatech
does not use it), I think should be reviewed/verified by NIC vendors using
it.
[Darrell] We need to confirm the masking in the flow (but from what I see, it
is ignored as Sugesh mentioned),
which would be a significant difference.
I guess we need input from Intel flow director folks to be sure
and check if this can be done otherwise.
What about the 82599 as another example ?
