Subject: [net PATCH v2 7/9] octeontx2-pf: mcs: Clear stats before freeing resource
From: Subbaraya Sundeep <sbhatta@...vell.com>
When freeing MCS hardware resources like SecY, SC and
SA the corresponding stats needs to be cleared. Otherwise
previous stats are shown in newly created macsec interfaces.
