Apologies the problem seems to be somewhere else altogether.
This is a temp fix in case someone runs into this issue.

libmnl-dev is already the newest version (1.0.4-2).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
I still dont know whats causing this problem, the CI does not detect
this failure as I am guessing its not built with this option on.
$ make DPDK_MLX5_PMD=y build-release
I will try to understand this, if anybody else understands whats going
please let me know.
Thank you
