If TP fetches an SRQ buffer but ends up not using it before the connection is aborted, then it passes the index of that SRQ buffer to the host in ABORT_REQ_RSS or ABORT_RPL CPL message. But, if the srqidx field is zero in the received ABORT_RPL or ABORT_REQ_RSS CPL, then we need to read the tcb.rq_start field to see if it really did have an RQE cached. This works around a case where HW does not include the srqidx in the ABORT_RPL/ABORT_REQ_RSS CPL. The final value of rq_start is the one present in TCB with the TF_RX_PDU_OUT bit cleared. So, we need to read the TCB, examine the TF_RX_PDU_OUT (bit 49 of t_flags) in order to determine if there's a rx PDU feedback event pending.
