1. Feature Overview:
Feature Id:	[201110]
a. Name of Feature:	Broadcom iSCSI support - bnx2i / cnic
b. Feature Description
Broadcom recently submitted their iSCSI code for bnx2 based controllers to the open source
community. Most System x servers have these controllers embedded on system boards. We are requesting
that this driver support (bnx2i / cnic) be integrated into distro releases. Patches submitted
 upstream 04/24/09:
 
 http://marc.info/?l=linux-netdev&m=124053572615059&w=2, 
 http://marc.info/?l=linux-netdev&m=124053572515053&w=2, 
 http://marc.info/?l=linux-netdev&m=124053572715062&w=2,

 http://marc.info/?l=linux-netdev&m=124053572415050&w=2. 
 
 cnic driver controls bnx2 h/w rings/resources, creates UIO interface for non-offload packets. bnx2i
driver is the iscsi component and interfaces with h/w through cnic.

Additional Comments:	Code is now accepted upstream and queued up for 2.6.31.

2. Feature Details:
Sponsor:	xSeries
Architectures:
x86
x86_64

Arch Specificity: Purely Common Code
Affects Kernel Modules: Yes
Delivery Mechanism: Direct from community
Category:	xSeries
Request Type:	Driver - Feature from Upstream
d. Upstream Acceptance:	Accepted
Sponsor Priority	1
f. Severity: High
IBM Confidential:	no
Code Contribution:	no
g. Component Version Target:	2.6.31

3. Business Case
Customers with System x servers containing planar-embedded Broadcom 570X NICs will be able to have
'built-in' iSCSI support.

Benefits
Enable iSCSI support on network interfaces (bcm5706, bcm5708) prevalent on most System x servers.
