[PATCH] net/iavf: fix SCTP tunnel packet forwarding issue

[Wenzhuo Lu]

The SCTP tunnel packets cannot be forwarded in AVX2 mode.

As 2 features are developed in parallel, 5712bf9d6e14
("net/iavf: add Tx AVX2 offload path") doesn't consider
the impact of 4f8259df563a ("net/iavf: enable Tx outer
checksum offload on AVX512"). So, the wrong TX path is
selected.

Fixes: 5712bf9d6e14 ("net/iavf: add Tx AVX2 offload path")
