Thanks for offering to take a look. I'm not sure if you've seen the rest of
this conversation already from it being on the ci mailing list or not, but
modinfo looks good for qat_c62x andqat_c62xvf after the custom kernel was
built. From there, it should be possible to bind some VFs for each PF on
the QAT card, per documentation here
https://doc.dpdk.org/guides/cryptodevs/qat.html but it results in a seg
fault like you see above. Let me know if you have any ideas.
