From: Satheesh Paul <psatheesh@marvell.com>

Add ROC API to free the given MCAM entry. If the MCAM
entry has flow counter associated, this API will clear
and free the flow counter.

Add ROC API to free the given MCAM entry. If the MCAM
entry has flow counter associated, this API will clear
and free the flow counter.
