replaced by commit 114f2830d
Some patches had to be modified to work with changed upstream source:
380-disable_ctrl_iface_mib.patch (adding more ifdef'ery)
plus some minor knits needed for other patches to apply which are not
worth being explicitely listed here.
For SAE key management in mesh mode, use the newly introduce
sae_password parameter instead of the psk parameter to also support
SAE keys which would fail the checks applied on the psk field (ie.
length and such). This fixes compatibility issues for users migrating
from authsae.

There was already a check -for this for TPK M2 (retries of that message are ignored completely), so -that behavior does not get modified. - -For TPK M3, the TPK-TK could have been reconfigured, but that was -followed by immediate teardown of the link due to an issue in updating -the STA entry.
