Eariler the SDK stat polling was erroneously set to once every msec
which is far more frequent than required by SWSS. The new setting, which
is consistent with other vendor SKUs, is once a second. The net result
is reduced CPU MHz by syncd.
For 7800 LCs, set LAG mode to support 1024 number of 16-member system
LAGs.
Why I did it
The SOC property changes are necessary to match #10519 which increases the number of system LAG IDs to 1024.
Description for the changelog
For 7800 LCs, set LAG mode to support 1024 number of 16-member system
LAGs.
