Thanks @saksarav-nokia, looks like this change was part of a SAI 7.1 update PR 13346 master and 202205 was using different SAI versions, SAI 7.1 was used for 202205 alone. Hence this PR was not merged into master first and cherry-picked to 202205 branch. |

Why I did it
The SAI code was modified to trap and drop the packets if the MAC_SA==MAC_DA and soc variable sai_disable_srcmacqedstmac_ctrl=1 needs to be set in bcm config. There was a PR #13346 which added updated bcm config in 202205, but never merged to master.
