Why I did it XGS saibcm-modules 8.4 is needed. #14471 Work item tracking Microsoft ADO (number only): 24917414 How I did it Copy files from xgs SDK 8.4 repo and modify makefiles to build the image. Upgrade version to 8.4.0.2 in saibcm-modules.mk. How to verify it Build a private image and run full qualification with it: https://elastictest.org/scheduler/testplan/650419cb71f60aa92c456a2b
