Subject: [PATCH iwl-net 0/4] idpf: fix issues in the reset handling path

Resolve multiple issues in the error path of reset handling of the IDPF
driver:
- Mailbox timeouts in the init task during a reset lead to the netdevs
  being unregistered.
- Reset times out and leaves the netdevs exposed to callbacks with the
  vport resources already freed.
- Simultaneous reset and soft reset calls will result in the loss of the
  vport state, leaving the netdev in DOWN state.
- Memory leak in idpf_vport_rel() where vport->rx_ptype_lkup was not
  freed during a reset.
- Memory leak in idpf_vc_core_deinit(), where kfree() was missing for
  hw->lan_regs.

Emil Tantilov (4):
  idpf: keep the netdev when a reset fails
  idpf: detach and close netdevs while handling a reset
  idpf: fix memory leak in idpf_vport_rel()
  idpf: fix memory leak in idpf_vc_core_deinit()
