l2tp: remove switch block in l2tp_nl_cmd_session_create()
Remove the switch block in l2tp_nl_cmd_session_create() that checks pseudowire-specific parameters since just L2TP_PWTYPE_ETH and L2TP_PWTYPE_PPP are currently supported and no actual checks are performed. Moreover the L2TP_PWTYPE_IP/default case presents a harmless issue in error handling (break instead of goto out_tunnel) Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@redhat.com> Acked-by: Guillaume Nault <g.nault@alphalink.fr> Signed-off-by: David S.
