Neels Hofmeyr gerrit-no-reply at lists.osmocom.orgHello Jenkins Builder, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/734 to look at the new patch set (#8). IuPS: dev hack: init hardcoded Ki on ATT REQ DEVELOPMENT HACK: Our current HLR does not support 3G authentication tokens. A new HLR/VLR implementation is being developed. Until it is ready and actual milenage authentication is properly supported, we are hardcoding a fixed Ki and use 2G auth.
