Subject: [PATCH AUTOSEL 4.19 004/671] ixgbe: don't clear IPsec sa counters on HW clearing

From: Shannon Nelson <shannon.nelson@...cle.com>

[ Upstream commit 9e3f2f5ecee69b0f70003fb3e07639151e91de73 ]

The software SA record counters should not be cleared when clearing
the hardware tables.  This causes the counters to be out of sync
after a driver reset.

Fixes: 63a67fe229ea ("ixgbe: add ipsec offload add and remove SA")
