I've just built OpenWrt for MIPS malta (BE) with mac80211-hwsim and
hereby confirm the problem shows up there in exactly the same way.
Also on MIPS malta with mac80211-hwsim, mesh with SAE works with
WolfSSL up to and including hostapd git revision 2b84ca4dd work fine,
starting from revision 6c9543fcb7 don't.

As OpenWrt might not be what you want for QA, I've been following
https://markuta.com/how-to-build-a-mips-qemu-image-on-debian/
and ended up with a functional Debian install inside QEMU about 20
minutes later. (I had to replace kernel image vmlinux-4.9.0-6-4kc-malta
mentioned in that guide with vmlinux-4.19.0-9-4kc-malta which is the
current version and exists on Debian's download server)
This would allow to run the whole test-suite as-is on MIPS32 BE, maybe
even with buildbot.w1.fi...

If there is anything else I can do to help debugging this, let me know.

Thank you!

Best regards

Daniel
