The new FCoE CNA's ( Converged Network Adapters ) support an ethernet function too which requires it's own driver. This driver, QLGE, is upstream in 2.6.28. BZ's 475662 and 475660 are feature requests from IBM for this functionality on their new blade servers. Redhat will require a hardware upgrade for their current blade server test systems in order to test this product.

Updating PM score.
This enhancement request was evaluated by the full Red Hat Enterprise Linux team for inclusion in a Red Hat Enterprise Linux minor release. As a result of this evaluation, Red Hat has tentatively approved inclusion of this feature in the next Red Hat Enterprise Linux Update minor release. While it is a goal to include this enhancement in the next minor release of Red Hat Enterprise Linux, the enhancement is not yet committed for inclusion in the next minor release pending the next phase of actual code integration and successful Red Hat and partner testing.

------- Comment From leitao.ibm.com 2009-05-21 12:07 EDT------- Red Hat, I didn't see the qlge driver on -148 yet. When did you plan to release the driver in the kernel releases ? Thanks Breno
The driver originally submitted by qlogic was not acceptable to us for a variety of reasons (the main one being the driver did not support NAPI). We hope it will be ready soon.
Created attachment 346799 [details] reformatted and updated to p12 This driver was reformatted and updated to version P12.
------- Comment From daisyc.com 2009-06-08 14:44 EDT------- Red Hat, We just want to let you know that we are monitoring Qlogic's qlge driver RHEL5.4 situation as we are very concerned about it. One of our 3Q Power IO hardware GA items is depending on this feature. We understand that you are in a reviewing process with Qlogic in determining the inclusion of the driver. We at IBM are working with Qlogic through daily meetings to try to see them through this process. We are offering our engineers and Power system/adapter equipment to do additional verifications on every one of their codedrops, hoping that it can help on building the confidence level on the quality of the code. Please do not hesitate to let us know if there is anything that we can help to make sure that Qlogic can make progress on this. Thanks.
Created attachment 347230 [details] P4 version This is version p4. it contains fixes suggested by Neil Horman.
I think this should be in POST. Marcus, correct me if I'm wrong here.

------- Comment From pbogdanovic.com 2009-07-13 20:12 EDT------- I have been working with the monteo daughter card and the qlge driver in 2.6.18-156 in the bladeceterH in EL9. I performed TCP_STREAM and TCP_MAERTS tests. Early results are that the send performance seems to be very good, 7-9 Gb/s depending on the system receiving the steam. When the monteo is receiving the tcp stream the performance is always pretty lousy about 3.5 Gb/s. I should make sure that I have the latest firmware and try again. This is just what first touch testing revealed.
The snap 3 build will contain patches to provide msix functionality. It should be available in a day or two. Perhaps this will improve read thruput.
Verified by RedHat, IBM and QLogic.
Verified the patch to this bug is included in kernel-2.6.18-160.el5
