These are additional patches for SRIOV support that came in after my primary patch set was submitted for review.
Comment 2 Doug Ledford 2012-03-20 16:17:05 UTC 
The final set of patches I'm submitting are done.
Comment 4 Aristeu Rozanski 2012-03-23 19:32:18 UTC

Comment 7 Zhang Kexin 2012-05-22 03:36:40 UTC 
Hi Vladimir,
Could  you help testing this bug on latest snapshot please? Thank you!
Comment 8 Weibing Zhang 2012-05-24 10:18:43 UTC 
It seems there is no num_vfs option for mlx4_en module. Can SR-IOV support for mlx4_en be tested via mlx4_core?

Comment 9 Doug Ledford 2012-05-29 18:26:25 UTC 
It is standard that the num_vfs option is set via mlx4_core.
Comment 10 Weibing Zhang 2012-06-01 09:45:15 UTC 
Run NIC driver test for mlx4_en on kernel-2.6.32-272 and all the tests passed.
[root@rdma4 ~]# modprobe -r mlx4_en
[root@rdma4 ~]# modprobe -r mlx4_ib
[root@rdma4 ~]# modprobe -r mlx4_core
[root@rdma4 ~]# modprobe mlx4_core num_vfs=1
Set SanityOnly.
