[PATCH 0/3 2.6.29] cxgb3i -- open-iscsi initiator acceleration 

From: Karen Xie <kxie@chelsio.com>

Hi, everyone,

This patchset is for 2.6.29.

It is based on the cxgb3i branch of Mike's linux-2.6-iscsi tree. It needs the
patch Mike sent several days ago on preparing the iscsi core libary for pdu
offload (http://marc.info/?l=linux-scsi&m=122819956917473).

The cxgb3i driver, especially the part handles the offloaded iscsi tcp
connection mangement, has gone through the netdev review (
http://marc.info/?l=linux-netdev&m=121944339211552,
http://marc.info/?l=linux-netdev&m=121989660016124).

The cxgb3i driver provides iscsi acceleration (PDU offload and payload data
direct placement) to the open-iscsi initiator. It accesses the hardware through
the cxgb3 module.

Thanks.
Karen

If this dependency exists I probably can't pull this into the
net-next-2.6 then, just FYI but you probably already understand
this :-)

Hi, Dave & Mike,

I guess I need some clarification on how this driver code could be merged.

The cxgb3i driver addition consists of 2 parts:

1. the new cxgb3i driver. It resides under drivers/scsi, this part has the dependency on the open-iscsi core changes I referred in the previous email. I was under the impression this goes into scsi-misc?

2. some iscsi related changes in cxgb3 driver (driver/net). This part does not have any dependency. Dave, I suppose this part goes into net-next? If so, this does not need Mike's patch at all.

Thanks a lot.
Karen

I think you want to send a patch with the entire driver like you were 
before. Do not send against my branch so James and others do not have to 
dig around in there.

There is no dependency with network stuff right (just the cxgb3 driver 
which is upstream already)? If so I think it would be easier to just 
send the driver through James.

Hi, Mike,

Thanks for the reply.

True, there is no dependency on the network driver part.

I will send out the new patch with the entire driver soon.

Thanks,
Karen
