Subject: [PATCH] net/mlx5: fix ipool memory leak
Date: Wed, 23 Jul 2025 09:49:22 +0300 [thread overview]
Message-ID: <20250723064923.1805575-1-rongweil@nvidia.com> (raw)
When ipool debug is enabled, there is internal memory
to maintain the ipool cache allocation. Need to free it
when destroying the ipool.
Fixes: 3a2bda363 ("net/mlx5: add ipool debug checks")
