I'm not sure if these validations must be here. There is an design discussion for overall Config validator and I don't think we need to scatter these checks in multiple places.

'show mac' performance improvement
1564302 
'show mac' was taking a lot of time to display the fdb entries when a large number of entries are present.
Using redis pipeline, reduced the time significantly.
Earlier it used to take about 10 minutes to show 32K MAC. After the fix it takes about 17-20 seconds.

Hi @stcheng and @prsunny,

I just reverted the previous changes for validations and added a new file fdbshow for 'show mac' performance enhancements. Please review the changes.

In case you want to consider the validations changes, let me know, I will readd the changes in that case.

Thanks.

Hi all
I notice that "A Static FDB entry should be configurable in hardware from CLI" was mentioned in SONiC Layer 2 Forwarding Enhancements HLD.md.
Wonder why this pull was not be merged which contain SONiC-CLI to config static FDB? Without this pull,how could I add a static FDB from CLI?
