Dmytro Linkin a5ae8fc905 net/mlx5e: Don't create devices during unload flow ... Running devlink reload command for port in switchdev mode cause resources to corrupt: driver can't release allocated EQ and reclaim memory pages, because "rdma" auxiliary device had add CQs which blocks EQ from deletion. Erroneous sequence happens during reload-down phase, and is following: 1. detach device - suspends auxiliary devices which support it, destroys others. During this step "eth-rep" and "rdma-rep" are destroyed, "eth" - suspended. 2. disable SRIOV - moves device to legacy mode; as part of disablement - rescans drivers. This step adds "rdma" auxiliary device. 3. destroy EQ table - <failure>. Driver shouldn't create any device during unload flows. To handle that implement MLX5_PRIV_FLAGS_DETACH flag, set it on device detach and unset on device attach. If flag is set do no-op on drivers rescan.
