[PATCH 02/11] net/dpaa2: fix rx error queue memory leak on port close

Maxime Leroy
2026-02-18T16:05:13Z

The rx_err_vq is allocated separately with rte_zmalloc() in
dpaa2_alloc_rx_tx_queues(), but dpaa2_free_rx_tx_queues() only frees
its q_storage contents via dpaa2_queue_storage_free() — the struct
dpaa2_queue itself is never freed, leaking memory on every port close.

Add the missing rte_free() and NULL assignment.
