Bug ID	1647
Summary	uio_pci_generic module bind failed in X710/XL710/XXV710
Product	DPDK
Version	unspecified
Hardware	All
OS	All
Status	UNCONFIRMED
Severity	normal
Priority	Normal
Component	ethdev
Assignee	dev@dpdk.org

Target Milestone	---

The uio_pci_generic module is not =
supported by XL710, since the errata of XL710
states that the Interrupt Status bit is not implemented. The errata is the =
item
#71 from the xl710 controller spec. The hw limitation is the same as other
X710/XXV710 NICs.

Implication:
When use --bind=3Duio_pci_generic, the uio_pci_generic module probes device=
 and
check the Interrupt Status bit. Since it is not supported by X710/XL710/XXV=
710,
it return a failed value. The statement that these products don=E2=80=99t s=
upport INTx
masking, is indicated in the related linux kernel commit.

Resolution/Workaround:
Do not bind the uio_pci_generic module in X710/XL710/XXV710 NICs.

Affected Environment/Platform:
All.

Driver/Module:
Poll Mode Driver (PMD).
