IB/srp: Split send and recieve CQs to reduce number of interrupts
We can reduce the number of IB interrupts from two interrupts per srp_queuecommand() call to one by using separate CQs for send and receive completions and processing send completions by polling every time a TX IU is allocated. Receive completion events still trigger an interrupt. Signed-off-by: Bart Van Assche <bart.vanassche@gmail.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
