Hi the open-fcoe experts:
I'm working on the FCoE initiator offload(performance) test on Linux 
with Intel ixgbe (Niantic 82599 driver).
Could you guys give me some instruction about what kind of prerequisite 
must to be done for
this offload(performance) test .

Based on my knowledge , following is my steps to do the offload test. 
(eth4 is the ixgbe interface)
1. service dcbd start
2. ifconfig eth4 mtu 2500
3. [r...@petpig ~]# dcbtool sc eth4 dcb on
Version:       2
Command:       Set Config
Feature:       DCB State
Port:          eth4
Status:        Successful
4. fcoeadm -c eth4
-----------------------------------------------------------
environment is :
The target is Sun storageTek 6140 array
FCoE switch is Cisco Nexus .
self-build kernel version : 2.6.31 i386
fcoe-utils: open-fcoe-2.6.30.tar.gz

The performace data(by iometer/vdbench) I got after doing the steps 
above is not very well, so I was wondering if the dcbx ON the interface
can 100%  guarantee the hardware's offload is enabled ? or some other 
critical steps I missed ? what kind of way I can
double check if the hardware's (Niantic ixgbe) offload is enabled or not ?.

as far as I can see is one message from dmesg:
ixgbe: eth4: ixgbe_set_fcoe_queues: FCOE enabled with DCB

Really really appreciate any comments/instructions/suggestions you can 
offer me to help me move on , thanks !

/Carol
