[PATCH] IB/mthca: assign ACK timeout field correctly
The hardware reads the ACK timeout field from the most significant 5 bits of struct mthca_qp_path's ackto field, not the least significant bits. This fix has the driver put the timeout in the right place. Without this, we get a timeout that is 2^8 times too small. Signed-off-by: Roland Dreier <rolandd@cisco.com>
