| Subject: [PATCH] bnxt_en: Improve device shutdown method. |
| |
| commit 5567ae4a8d569d996d0d88d0eceb76205e4c7ce5 upstream. |
| |
| Especially when bnxt_shutdown() is called during kexec, we need to |
| disable MSIX and disable Bus Master to completely quiesce the device. |
| Make these 2 calls unconditionally in the shutdown method. |
| |
| Fixes: c20dc142dd7b ("bnxt_en: Disable bus master during PCI shutdown and driver unload.") |
