Hello everybody,
We are trying to set up FPP with SR-IOV using different amounts of virtual functions on 82599EB 10G-Cards.
Unfortunately we get extensive packet loss (50-99%) receiving at rates over 1.19Mpps.
This does not happen if no virtual functions are used at all (rates up to 14.4Mpps with negligible packet loss).
We are using the following drivers:
ixgbe:
| filename: | /lib/modules/2.6.32-358.11.1.el6.x86_64/kernel/drivers/net/ixgbe/ixgbe.ko |
| version: | 3.16.1 |

ixgbevf:
| filename: | /lib/modules/2.6.32-358.11.1.el6.x86_64/kernel/drivers/net/ixgbevf/ixgbevf.ko |
| version: | 2.6.0-k |

Does someone have further information about this issue and about how to reach higher receiving speeds without packet loss?
Thank you and best regards,
Richard
