From de3d353072f9342f04112ba0504c3e294220cb8f Mon Sep 17 00:00:00 2001 From: Steve Wise Date: Mon, 14 May 2007 13:27:27 -0500 Subject: RDMA/cxgb3: Streaming -> RDMA mode transition fixes Due to a HW issue, our current scheme to transition the connection from streaming to rdma mode is broken on the passive side. The firmware and driver now support a new transition scheme for the passive side: - driver posts rdma_init_wr (now including the initial receive seqno) - driver posts last streaming message via TX_DATA message (MPA start response) - uP atomically sends the last streaming message and transitions the tcb to rdma mode. - driver waits for wr_ack indicating the last streaming message was ACKed. NOTE: This change also bumps the required firmware version to 4.3.
