IB/core, opa_vnic, hfi1, mlx5: Properly free rdma_netdev
IPOIB is calling free_rdma_netdev even though alloc_rdma_netdev has returned -EOPNOTSUPP. Move free_rdma_netdev from ib_device structure to rdma_netdev structure thus ensuring proper cleanup function is called for the rdma net device. Fix the following trace: ib0: Failed to modify QP to ERROR state BUG: unable to handle kernel paging request at 0000000000001d20 IP: hfi1_vnic_free_rn+0x26/0xb0 [hfi1] Call Trace: ipoib_remove_one+0xbe/0x160 [ib_ipoib] ib_unregister_device+0xd0/0x170 [ib_core] rvt_unregister_device+0x29/0x90 [rdmavt] hfi1_unregister_ib_device+0x1a/0x100 [hfi1] remove_one+0x4b/0x220 [hfi1] pci_device_remove+0x39/0xc0 device_release_driver_internal+0x141/0x200 driver_detach+0x3f/0x80 bus_remove_driver+0x55/0xd0 driver_unregister+0x2c/0x50 pci_unregister_driver+0x2a/0xa0 hfi1_mod_cleanup+0x10/0xf65 [hfi1] SyS_delete_module+0x171/0x250 do_syscall_64+0x67/0x150 entry_SYSCALL64_slow_path+0x25/0x25 Reviewed-by: Dennis Dalessandro <dennis.dalessandro@intel.com> Signed-off-by: Niranjana Vishwanathapura <niranjana.vishwanathapura@intel.com> Signed-off-by: Dennis Dalessandro <dennis.dalessandro@intel.com> Signed-off-by: Doug Ledford <dledford@redhat.com>
