    SR-IOV failed on Intel Xeon-D 1541's X552 10gbe NIC


      Hi all,


      I cannot figure out why I cannot enable SR-IOV on Intel Xeon-D 1541's X552 10gbe NIC, it must be the intel's latest ixgbe driver issue because on the same SoC board, the Intel i350 1gbe NIC's sr-iov can be enabled.


      Following is the pci device info and also its ixgbe info
