int qib_make_rc_req

(

struct qib_qp *

qp

)

qib_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 qib_ib_header *	hdr,
		int	has_grh,
		void *	data,
		u32	tlen,
		struct qib_qp *	qp
	)

qib_rc_rcv - process an incoming RC packet : the context pointer : 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 qib_qp_rcv() to process an incoming RC packet for the given QP. Called at interrupt level.

void qib_send_rc_ack

(

struct qib_qp *

qp

)

qib_send_rc_ack - Construct an ACK packet and send it : a pointer to the QP

This is called from qib_rc_rcv() and qib_kreceive(). Note that RDMA reads and atomics are handled in the send side QP state and tasklet.
