ABI version on build machine and target machine

[Antonio Di Bacco]

I have an application that is built with version 21.11.0 of the DPDK (ABI22).
Now I run the application  on a target machine that has 21.11.2
installed, then the same ABI.

How can I be sure that the DPDK inlined source code in 21.11.0 is the
same or compatible with that in 21.11.2?
I mean, if an inline function in version 21.11.0 has changed in
21.11.2, could I see problems?

Is this important or the fact that the two DPDKs have the same ABI
grants that everything will work?
