From ec1d1d2302067e3ccbc4d0adcd36d72410933b70 Mon Sep 17 00:00:00 2001 From: Vignesh Sridhar Date: Wed, 29 Jul 2020 17:19:15 -0700 Subject: ice: Clear and free XLT entries on reset This fix has been added to address memory leak issues resulting from triggering a sudden driver reset which does not allow us to follow our normal removal flows for SW XLT entries for advanced features. - Adding call to destroy flow profile locks when clearing SW XLT tables. - Extraction sequence entries were not correctly cleared previously which could cause ownership conflicts for repeated reset-replay calls.
