Why this remained as libsaibcm-dev_4.3.3.4_amd64.deb instead of libsaibcm-dev_4.3.3.4-1_amd64.deb ??

Looks like you forgot to update the corresponding debian/changelog file for the new version. Please add that and rebuild. and make the change available to both REL_4.3.3 and REL_4.3.3-202012 branches.

This is the SAI 4.3.3.5 code drop from BRCM to address 2 CSP case and initial MMU changes Note the MMU changes is the same as that of SAI 4.3.3.4-1 (#7341) but with official patch. - Case CS00012178716 [4.3] Polling SAI_QUEUE_STAT_SHARED_WATERMARK_BYTES fails often on TH3 - Case CS00012159273 [4.3.3.3] [TD3][IPFWD] subnet broadcast flooding end with extra VLAN Tag if member port of VLAN interface deleted then added back to VLAN Once we have this PR merged, will validate each one of the above to ensure they are indeed fixed... Preliminary tests looks fine. BGP neighbors were all up with proper routes programmed interfaces are all up Manually ran the following test cases on TD3 DUT and all passed: ipfwd/test_dir_bcast.py fib/test_fib.py vxlan/test_vxlan_decap.py decap/test_decap.py fdb/test_fdb.py
