            Bug ID: 1632
           Summary: Some hardware off-load functions are not supported by
                    the VF Driver
           Product: DPDK
           Version: unspecified
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: vhost/virtio
          Assignee: dev at dpdk.org
          Reporter: nandinipersad361 at gmail.com
  Target Milestone: ---

Currently, configuration of the following items is not supported by the VF
driver:

IP/UDP/TCP checksum offload

Jumbo Frame Receipt

HW Strip CRC

Implication:
Any configuration for these items in the VF register will be ignored. The
behavior is dependent on the current PF setting.

Resolution/Workaround:
For the PF (Physical Function) status on which the VF driver depends, there is
an option item under PMD in the config file. For others, the VF will keep the
same behavior as PF setting.

Affected Environment/Platform:
All.

Driver/Module:
VF (SR-IOV) Poll Mode Driver (PMD).
