[dpdk-dev] DPDK2.1 VF and NIC X552 PF - ixgbe SRIOV works?

[Zhongliang Shu <zshu11@yahoo.com>]

Hi, Guys:
I have developed a VM to use SRIOV VF of DPDK2.1 libraryand its PF NIC is interl X552 NIC. The VM is deployed on KVM on Linux box.
NIC Inforoot@localhost:~# modinfo ixgbe
filename:       /lib/modules/3.14.49-rt46-WR7.0.0.5_ovp/kernel/drivers/juniper/x552-nic/ixgbe.ko
version:        4.2.0.4.1-unreleased
license:        GPL

When the VM start, and its correct corresponding MAC is pushed into PF.

Several questions about the log msgs
1): its keep to see the log msgs:     [63289.573419] ixgbe 0000:03:00.0 sxe0: VF Reset msg received from vf 2
     [63290.033229] ixgbe 0000:03:00.0 sxe0: VF Reset msg received from vf 2    what reason cause these msg?
2): When try ping from the VM,   it fails and there has msg:
      [63953.063867] ixgbe 0000:03:00.0: Malicious event on VF 2 tx:100000 rx:0 
    what reason causes this msg?
3): Does DPDK2.1 VF and X552 PF is tested and supported?
By the way, the SRIOV of this VM work fine for X550 NIC and  82580 NIC,
Thanks.
