qib_uc_rcv - handle an incoming UC packet : the port the packet came in on : the header of the packet : true if the packet has a GRH : the packet data : the length of the packet : the QP for this packet.
This is called from qib_qp_rcv() to process an incoming UC packet for the given QP. Called at interrupt level.

qib_verbs_send - send a packet : the QP to send on : the packet header : the number of 32-bit words in the header : the SGE to send : the length of the packet in bytes
Return zero if packet is sent or queued OK. Return non-zero and clear qp->s_flags QIB_S_BUSY otherwise.
