[pci PATCH v8 2/4] ena: Migrate over to unmanaged SR-IOV support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Instead of implementing our own version of a SR-IOV configuration stub in
the ena driver we can just reuse the existing
pci_sriov_configure_simple function.

v5: Replaced call to pci_sriov_configure_unmanaged with
        pci_sriov_configure_simple
v6: Dropped "#ifdef" checks for IOV wrapping sriov_configure definition
v7: No change
