When an application aborts the connection by moving QP from RTS to ERROR, then iw_cxgb4's modify_rc_qp() RTS->ERROR logic sets the *srqidxp to 0 via t4_set_wq_in_error(&qhp->wq, 0), and aborts the connection by calling c4iw_ep_disconnect(). c4iw_ep_disconnect() does the following: 1. sends up a close_complete_upcall(ep, -ECONNRESET) to libcxgb4. 2. sends abort request CPL to hw. But, since the close_complete_upcall() is sent before sending the ABORT_REQ to hw, libcxgb4 would fail to release the srqidx if the connection holds one. Because, the srqidx is passed up to libcxgb4 only after corresponding ABORT_RPL is processed by kernel in abort_rpl(). This patch handle the corner-case by moving the call to close_complete_upcall() from c4iw_ep_disconnect() to abort_rpl(). So that libcxgb4 is notified about the -ECONNRESET only after abort_rpl(), and libcxgb4 can relinquish the srqidx properly.
