See patch: http://patches.dpdk.org/patch/44129/

Basically, the experimental_apis setting was not getting passed through and
used by the base code libraries when set at the higher level, since they
were being built individually by the respective base/meson.build files,
rather than by the main driver build loop. Putting in an explicit check for
the value in the base code files should make your life easier here. You
just need to ensure that the "allow_experimental_apis" setting is set
*before* the call to "subdir(base)" e.g. in ixgbe, it's currently after and
needs to be moved by your patchset.

PS: I also notice that i40e is using the experimental APIs cflags directly,
rather than the variable, I'll have to fix that in a later patch.
