Such options can come in any QP state, so add in/out fields to set and query ECE options. OUT fields: * create_qp()/create_dct() - default ECE options for that type of QP. * modify_qp() - enabled ECE options after QP state transition. IN fields: * create_qp()/create_dct() - create QP with this ECE option. * modify_qp() - requested options. For unconnected QPs, the FW will return an error if ECE is already configured with any options that not equal to previously set.
