This topic has previously been discussed in another context - adding external libraries [1]. Like you do here, I generally preferred #ifdefs in the code, but the majority preferred stubs "promoting improved code readability". I might argue that Tyler is following that guidance here; and perhaps the decision should be reconsidered, now that we have a real-life example of how it affects code readability. ;-) [1]: https://inbox.dpdk.org/dev/20240109141009.497807-1-jer...@marvell.com/
