Subject: [dpdk-stable] [PATCH v2 7/8] net/ice/base: clear and free XLT entries on reset
Date: Wed,  1 Jul 2020 13:49:50 +0800
Message-ID: <20200701054951.2393-8-qi.z.zhang@intel.com> (raw)
In-Reply-To: <20200701054951.2393-1-qi.z.zhang@intel.com>

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.

Fixes: 969890d505b1 ("net/ice/base: enable clearing of HW tables")
