This works fine in my tests with 4.3.0. All the mac80211_hwsim test
cases for mesh pass with the current wpa_supplicant snapshot built with

Can you please share some more details on how you are testing this and
ideally, debug logs from two devices for a case that fails with WolfSSL,
but works with OpenSSL? I'd like to also get a confirmation that you are
seeing the issue with the current snapshot of the master branch in
hostap.git since that is the version I would be using for any debugging
of the issue.
