don't see anything private that shouldn't be public in the tracker here...)

(2) comes down to breakage in DPDK 19.11.4 linking.
I've reported that at:
and Luca will take care of that.

Back to the OVS config problem, I've reproduced and found that it is
indeed toolchain related (affects old and new versions of OVS).
It seems it is indeed a problem in libdpdk-dev

$ cat /usr/lib/x86_64-linux-gnu/pkgconfig/libdpdk.pc
Libs: -L${libdir} [...] -lnuma -lpcap -lIPSec_MB

The above path shouldn't be there as-is.
It should not be versioned to ...-gnu/9/../ which is what fails now
that we are on gcc-10.

I need to look if I can find where exactly this comes from ...
