HKV1 does not have support to maintain per pdev AST table.
Hence workaround is required to ensure that AST entry is deleted before
adding an entry with same MAC. This syncronization needs to done across
pdev. This workaround in required on for HKV1, add changes to enable
workaround only for HKV1 and disabled for other platforms.
