Subject: [PATCH 02/10] IB/mthca: assign ACK timeout field correctly
Date: Tue, 20 Sep 2005 15:08:10 -0700 [thread overview]
Message-ID: <2005920158.rJMu8Og0ayj9lKb3@cisco.com> (raw)
In-Reply-To: <2005920158.6GA97hjj1WYfaq3W@cisco.com>
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.
