Link for Legato-Dist-Source-mdm9x15-SWI9X15Y_07.04.06.00

I have downloaded the legato15.10-application framework and i want to download yocto for same version. In sierra source site they have updated everything for 16.01.

From where can i get a linux source distribution for 15.05 viz (Legato-Dist-Source-mdm9x15-SWI9X15Y_07.04.06.00.tar.bz2)
