2007-10-09RDMA/cxgb3: Make the iw_cxgb3 module parameters writableSteve Wise
Allow changing parameter values without having to reload the module. This is safe because these parameters are only looked at when a new connection is established. Signed-off-by: Steve Wise <swise@opengridcomputing.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>

2007-07-09RDMA/cxgb3: Don't abort after failures sending the mpa replySteve Wise
This bug results in an abort request being sent down _after_ the tid has been released. If the tid happens to have been reused, then the subsequent generation of the tid gets incorrectly aborted. The thread running iwch_accecpt_cr() must not abort a connection if an error is returned after being awakened. If any errors did occur while iwch_accept_cr() is blocked, then the connection has already been aborted on the thread processing the error.

2007-07-09RDMA/cxgb3: Don't post TID_RELEASE messageSteve Wise
The LLD does this for us in cxgb3_remove_tid(). Also fixed active open failure cases where we also shouldn't be releasing the TID. Signed-off-by: Steve Wise <swise@opengridcomputing.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2007-07-09RDMA/cxgb3: Don't count neg_adv abort_req_rss messages as real abortsSteve Wise
Negative advice messages should _not_ count toward the 2 abort requests needed to indicate an abort request. Signed-off-by: Steve Wise <swise@opengridcomputing.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2007-07-09RDMA/cxgb3: Streaming -> RDMA mode transition fixesSteve Wise
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. Signed-off-by: Steve Wise <swise@opengridcomputing.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2007-05-06RDMA/cxgb3: Support for new abort logicSteve Wise
The HW now posts 2 ABORT_RPL and/or PEER_ABORT_REQ messages. We need to handle them by silenty dropping the 1st but mark that we're ready for the final message. This plugs some close races between the uP and HW. Also update the minimum required firmware version.

2007-04-25[SK_BUFF]: Introduce skb_copy_from_linear_data{_offset}Arnaldo Carvalho de Melo
To clearly state the intent of copying from linear sk_buffs, _offset being a overly long variant but interesting for the sake of saving some bytes. Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
2007-04-25[SK_BUFF]: Convert skb->end to sk_buff_data_tArnaldo Carvalho de Melo
Now to convert the last one, skb->data, that will allow many simplifications and removal of some of the offset helpers. Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-04-25[SK_BUFF]: Introduce skb_reset_transport_header(skb)Arnaldo Carvalho de Melo
For the common, open coded 'skb->h.raw = skb->data' operation, so that we can later turn skb->h.raw into a offset, reducing the size of struct sk_buff in 64bit land while possibly keeping it as a pointer on 32bit. This one touches just the most simple cases: skb->h.raw = skb->data; skb->h.raw = {skb_push|[__]skb_pull}() The next ones will handle the slightly more "complex" cases.

2007-04-12RDMA/cxgb3: Add set_tcb_rpl_handlerSteve Wise
As of commit 6cdbd77e ("cxgb3 - missing CPL hanler and register setting."), the cxgb3 ethernet NIC driver no longer handles SET_TCB replies, so we need to do it in the iWARP driver.

2007-03-06RDMA/cxgb3: Fixes for "normal close" failuresSteve Wise
Fixes for "normal close" failures: - Start normal close timer when moving to CLOSING state. - Handle ABORTING state in close_con_rpl(). - Stop timer correctly on abort during a normal close. Signed-off-by: Steve Wise <swise@opengridcomputing.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2007-03-06RDMA/cxgb3: Start ep timer on a MPA rejectSteve Wise
If the consumer rejects the connection we end up under-referencing the endpoint structure. The fix is to call iwch_ep_disconnect() instead of the low level disconnect functions so that the endpoint close timer is started correctly.
