thank you very much for the revert. I have compiled 6.8 with this patch
and attest that it solves my eduroam connection issue.

Tested-by: Karel Balej <balejk@xxxxxxxxx>

May I please ask, though, why you did not Cc stable (and add a Fixes
trailer for that matter)? It seems like something that would be nice to
see fixed in 6.7.y and 6.8.y too as soon as possible.

Kind regards,
K. B.
