It was mentioned in the release meeting call that they are new
regressions since 17.11.10-rc1 - these are the commits that were
backported that changed drivers/mlx*:

https://git.dpdk.org/dpdk-stable/commit/?h=17.11&id=60d0f2e079
https://git.dpdk.org/dpdk-stable/commit/?h=17.11&id=005b17cbab
https://git.dpdk.org/dpdk-stable/commit/?h=17.11&id=4cd784b02d
https://git.dpdk.org/dpdk-stable/commit/?h=17.11&id=569c98371e

They seem quite innocous to me, but I might be wrong. Authors and
reviewers CC'ed.

- there's no "off_t" reference in MLX4
- the only flow change was this commit and it seems unrelated:

https://git.dpdk.org/dpdk-stable/commit/?h=17.11&id=940d6c60d5748

So I'd imagine it could be some unrelated change, in the core
libraries, that causes these issues. Would you be able to bisect the
tree to see exactly which commits cause issues?

Thanks!
