int ipath_make_rc_req

(

struct ipath_qp *

qp

)

ipath_make_rc_req - construct a request packet (SEND, RDMA r/w, ATOMIC) : a pointer to the QP

Return 1 if constructed; otherwise, return 0.

		enum ib_wc_status	err

		struct ipath_ib_header *	hdr,
		int	has_grh,
		void *	data,
		u32	tlen,
		struct ipath_qp *	qp
	)

ipath_rc_rcv - process an incoming RC packet : the device this packet came in on : the header of this packet : true if the header has a GRH : the packet data : the packet length : the QP for this packet

This is called from ipath_qp_rcv() to process an incoming RC packet for the given QP. Called at interrupt level.

Definition at line 1570 of file ipath_rc.c.

void ipath_restart_rc	(	struct ipath_qp *	qp,
		u32	psn
	)

ipath_restart_rc - back up requester to resend the last un-ACKed request : the QP to restart : packet sequence number for the request : the work completion request

The QP s_lock should be held and interrupts disabled.
