How to enabe RSS in Cisco enic using UCS?

I need to enable RSS (receive-side scaling) on the enic interfaces in UCS. I followed the document at this link. However, all the interrupts are still being delivered on only one CPU. There are 8 CPU queues with 7 of them always empty. "ethtool -k" also shows rss as disabled. Any ideas?
 

Some details about the setup:

B200-M3

UCS version : Version 2.2 (1b)

enic driver version: 2.1.1.39

Operating System: CentOS 6.4 (kernel 2.6.32-358.2.1)

dmesg shows something like this:

[    8.344965] enic 0000:06:00.0: vNIC csum tx/rx yes/yes tso/lro yes/yes rss yes intr mode any type min timer 125 usec loopback tag 0x0000
[    8.344968] enic 0000:06:00.0: vNIC resources avail: wq 1 rq 24 cq 25 intr 32
[    8.345263] enic 0000:06:00.0: vNIC resources used:  wq 1 rq 8 cq 9 intr 11 intr mode MSI-X
[    8.353307] enic 0000:07:00.0: vNIC csum tx/rx yes/yes tso/lro yes/yes rss yes intr mode any type min timer 125 usec loopback tag 0x0000
[    8.353309] enic 0000:07:00.0: vNIC resources avail: wq 1 rq 24 cq 25 intr 32
[    8.353537] enic 0000:07:00.0: vNIC resources used:  wq 1 rq 8 cq 9 intr 11 intr mode MSI-X

 

ethtool output is this:

[admin@Col-Bench1 ~]# ethtool -k eth1
Features for eth1:
rx-checksumming: on
tx-checksumming: on

tcp-segmentation-offload: on
