From: Satha Rao <skotesh...@marvell.com>
This patch preferred user provided argument while configuring slack.
If no platform argument given then by default MAX(24, 30% of SQ size)
was configured as slack. Currently even if user provided SQB slack,
we take max of internally calculated value and user given one
