| Subject: cxgb4: Fix queue free path of ULD drivers |
| |
| From: Arjun Vynipadath <arjun@chelsio.com> |
| |
| [ Upstream commit d7cb44496a9bb458632cb3c18acb08949c210448 ] |
| |
| Setting sge_uld_rxq_info to NULL in free_queues_uld(). |
| We are referencing sge_uld_rxq_info in cxgb_up(). This |
| will fix a panic when interface is brought up after a |
| ULDq creation failure. |
| |
| Fixes: 94cdb8bb993a (cxgb4: Add support for dynamic allocation |
| of resources for ULD) |
