Hello,

In regards to the outer layers, having grepped through the code for
"[\w_]+_GOOD|[\w_]+_BAD", I wasn't able to find the flags that I expected.
I expected something like PKT_RX_OUTER_IP_CKSUM_BAD and
PKT_RX_OUTER_IP_CKSUM_GOOD to show up since that seems to be the format for
flags to be printed, but there wasn't anything in the grep output related
to that. Am I missing something? I can do outer UDP fairly easily, but it
doesn't look like there is support for outer TCP and outer SCTP in TestPmd.
I will plan to add tests

"UNKNOWN".

To clarify my meaning there, I mean that the verify statements in the test
case will abort the test on the first failed statement, so I am splitting
the tests up so that I don't need to collect all of the errors and then
spit them all out at once. Also, as far as I can tell, unknown only occurs
when it is not possible to decode a layer. The NIC I am testing with
doesn't support offloading outer udp, and TestPmd gives me an error message
and then leaves the option set to software mode. When I send a packet
without any tunneling, then it gives me something like
"PKT_RX_OUTER_L4_CKSUM_UNKNOWN". Is this assessment incorrect?

Could you please elaborate on this?

Thanks for your feedback
