OpenThread requires
otPlatCryptoPbkdf2GenerateKey
to be implemented by platform if PSA Crypto API is used. For ncs v2.6.0 PSA Crypto API doesn't yet fully support PBKDF2 generation. Because of that, callingotPlatCryptoPbkdf2GenerateKey
results withOT_ERROR_NOT_CAPABLE
error.This commit provides a patch that allows a fallback to legacy MbedTLS implementation that follows the one provided by OpenThread.
