-Virtio incorrect header length used if MSI-X is disabled by kernel driver
--------------------------------------------------------------------------
-
-+--------------------------------+--------------------------------------------------------------------------------------+
-| Title | Virtio incorrect header length used if
MSI-X is disabled by kernel driver or |
-| | if VIRTIO_NET_F_MAC is not negotiated.
|
-| |
|
-+================================+======================================================================================+
-| Reference # | IXA00384256
|
-| |
|
-+--------------------------------+--------------------------------------------------------------------------------------+
-| Description | The Virtio header for host-guest
communication is of variable length and |
-| | is dependent on whether MSI-X has been
enabled by the kernel driver for the network |
-| | device.
|
-| |
|
-| | The base header length of 20 bytes will be
extended by 4 bytes to accommodate MSI-X |
-| | vectors and the Virtio Network Device
header will appear at byte offset 24. |
-| |
|
-| | The Userspace Virtio Poll Mode Driver tests
the guest feature bits for the presence |
-| | of VIRTIO_PCI_FLAG_MISIX, however this bit
field is not part of the Virtio |
-| | specification and resolves to the
VIRTIO_NET_F_MAC feature instead. |
-| |
|
-+--------------------------------+--------------------------------------------------------------------------------------+
-| Implication | The DPDK kernel driver will enable MSI-X by
default, |
-| | however if loaded with ?intr_mode=legacy?
on a guest with a Virtio Network Device, |
-| | a KVM-Qemu guest may crash with the
following error: ?virtio-net header not in first |
-| | element?.
|
-| |
|
-| | If VIRTIO_NET_F_MAC feature has not been
negotiated, then the Userspace Poll Mode |
-| | Driver will assume that MSI-X has been
disabled and will prevent the proper |
-| | functioning of the driver.
|
-| |
|
-+--------------------------------+--------------------------------------------------------------------------------------+
-| Resolution | Ensure #define VIRTIO_PCI_CONFIG(hw)
returns the correct offset (20 or 24 bytes) for |
-| | the devices where in rare cases MSI-X is
disabled or VIRTIO_NET_F_MAC has not been |
-| | negotiated.
