Hi,
I'm using Intel's X520-SR2 NIC in SRIOV mode.
I'm able to attach Virtual functions in DomU HVM where ixegbevf driver is able
to transmit packet Inter-VF or outside but No VF is receiving packets.
I checked VF packet stats using ethtool both on PF and VF driver which
indicated incrementing packet count. But none of the packets are reaching
ixgbevf driver.
I disabled xen default s/w bridge to verify direct access to/from guest.
Since none of the ixgbevf's napi->poll method's are called, could this be a
Interrupt remapping issue or probably I'm missing to configure something. I'm
working to support S-VLAN bridging on NIC and any help is appreciated.
My environment details:
<HW>
2X Intel Xeon 5680
VT-d supported Intel 5520/5500 chipset.
<SW>
Patched Xen version :3.1.2-194.32.1.el5
kernel: 2.6.18-194.32.1.el5.centos.plusxen
Distro: CentOS5.5
PF driver: upgraded to 3.1.17
VF driver upgraded to 1.0.17
Note: DCA and IOAT is disabled.
Best Regards,
Manish Verma
