iwlwifi: pcie: restart the driver when a command times out
This should really not happen. If it does, restarting is the only way to recover since the driver and the firmware might very well be out of sync. Moreover, iwl_op_mode_nic_error will print data that might help debugging. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
