--- Comment #3 from Marius-Cristian Baciu (baciumariuscristian@yahoo.com) ---
Hi,

Unfortunately that patch only targets a memory socket issue with the ASO
mechanism. However, in my setup ASO is never an issue - I actually do not
believe it is enabled.

To give a little more insight, the problem I am describing manifests on the
data path:
- rte_eth_tx_burst();
- mlx5_tx_burst_*() is called;
- at some later point, in mr_lookup_caches(), mr_btree_lookup() returns
UINT32_MAX because all 256 entries in the cache have been occupied and last
memory registration did not catch an empty slot;
- when mr_lookup_caches() fails, mlx5_mr_create() -> mlx5_mr_create_primary()
is called;
- mlx5_malloc() at line 723 fails because it is called with an inappropriate
socket ID (the socket ID of the memseg list associated with an external buffer
(prior with rte_extmem_register()), EXTERNAL_HEAP_MIN_SOCKET_ID, which does not
actually have a valid heap associated, from which memory could be allocated.
