| Subject: netfilter: flowtable: Fix missing flush hardware on table free |
| |
| From: Paul Blakey <paulb@mellanox.com> |
| |
| commit 0f34f30a1be80f3f59efeaab596396bc698e7337 upstream. |
| |
| If entries exist when freeing a hardware offload enabled table, |
| we queue work for hardware while running the gc iteration. |
| |
| Execute it (flush) after queueing. |
| |
