[Fix]
Add NULL pointer checks in ice_vsi_set_napi_queues() to prevent crashes
during resume from suspend when rings[q_idx]->q_vector is NULL.
After wakeup from suspend, IRDMA is initialized with error:
kernel: ice 0000:60:00.0: IRDMA hardware initialization FAILED init_state=4
status=-110
kernel: irdma.gen_2 ice.roce.1: probe with driver irdma.gen_2 failed with
error -110
IRDMA times out because the initialization before the schedule reset.
Initialize RDMA after rebuild to fix it.
Patches:
https://lore.kernel.org/lkml/[email protected]/
[Test]
Suspend 30 times by the command:
$ sudo rtcwake -m mem -s 20
[Where problems could occur]
It may break intel ethernet driver ice.
The patches are reviewed in intel-wired-lan maillist, but not merged yet.
So SRU for oem-6.17 only for now.
