If anyone has any objections, please let me know. ------------------ From: Saeed Mahameed [ Upstream commit 5629f8859dca7ef74d7314b60de6a957f23166c0 ] Profile rollback can fail in mlx5e_netdev_change_profile() and we will end up with invalid mlx5e_priv memset to 0, we must maintain the 'destroying' bit in order to gracefully shutdown even if the profile/priv are not valid. This patch maintains the previous state of the 'destroying' state of mlx5e_priv after priv cleanup, to allow the remove flow to cleanup common resources from mlx5_core to avoid FW fatal errors as seen below: $ devlink dev eswitch set pci/0000:00:03.0 mode switchdev Error: mlx5_core: Failed setting eswitch to offloads. dmesg: mlx5_core 0000:00:03.0 enp0s3np0: failed to rollback to orig profile, ... $ devlink dev reload pci/0000:00:03.0 mlx5_core 0000:00:03.0: E-Switch: Disable: mode(LEGACY), nvfs(0), necvfs(0), active vports(0) mlx5_core 0000:00:03.0: poll_health:803:(pid 519): Fatal error 3 detected mlx5_core 0000:00:03.0: firmware version: 28.41.1000 mlx5_core 0000:00:03.0: 0.000 Gb/s available PCIe bandwidth (Unknown x255 link) mlx5_core 0000:00:03.0: mlx5_function_enable:1200:(pid 519): enable hca failed mlx5_core 0000:00:03.0: mlx5_function_enable:1200:(pid 519): enable hca failed mlx5_core 0000:00:03.0: mlx5_health_try_recover:340:(pid 141): handling bad device here mlx5_core 0000:00:03.0: mlx5_handle_bad_state:285:(pid 141): Expected to see disabled NIC but it is full driver mlx5_core 0000:00:03.0: mlx5_error_sw_reset:236:(pid 141): start mlx5_core 0000:00:03.0: NIC IFC still 0 after 4000ms.
