To all SR-IOV experts,
I want to use the SR-IOV functionality of Intel's PCI Express 82576 Ethernet NIC on a platform which does not support MSI-X interrupts but only MSI and legacy interrupts types of PCI.
Why are both igb and igbvf drivers requiring MSI-X for I/O virtualization?
In the PCI Express "Single Root I/O Virtualization and Sharing Specification" from PCI-SIG is mentioned, that MSI should be sufficient to use SR-IOV in general.
Any reason Intel decided to only use MSI-X?
Thanks,
Mr. Isfort
