Why I did it
In the case of ASIC detection failures on Broadcom (or if the ASIC couldn't be detected in time), the
/dev/shmpartition in the syncd container will be only 64MB, which might cause issues if syncd/Broadcom SAI library needs more space than that.Work item tracking
How I did it
Since using a larger
/dev/shmon its own doesn't cause any issues, bump up the default to 512MB. This should be enough for most platforms.How to verify it
Which release branch to backport (provide reason below if selected)
Tested branch (Please provide the tested image version)
