When I use the SR-IOV function of 82599, I allocated a VF to a VM under the XEN monitor in the host, and I have the following questions:
- Can the VM receive the frame with the VLAN tag head?
- Can the SR-IOV function of 82599 support FCoE( Fibre Channel over Ethernet)?
- When I replaced the switch which is directly connected to the host from Brocade 8000 to Brocade VBX 6730, the ixgbe driver have error messages like this:
ixgbe 0000:84:00.0: eth2: NIC Link is Up 10 Gbps, Flow Control: RX/TX
ixgbe 0000:84:00.0: eth2: detected SFP+: 5
ixgbe 0000:84:00.0: eth2: NIC Link is Up 10 Gbps, Flow Control: None
ixgbe 0000:84:00.0: eth2: detected SFP+: 5
ixgbe 0000:84:00.0: eth2: NIC Link is Up 10 Gbps, Flow Control: RX/TX
ixgbe 0000:84:00.0: eth2: detected SFP+: 5
ixgbe 0000:84:00.0: eth2: NIC Link is Up 10 Gbps, Flow Control: None
ixgbe 0000:84:00.0: eth2: detected SFP+: 5
and it repeated again and again. In addition, the host with the 82599 NIC can not ping other hosts. But everything turns normal without the SR-IOV function.
I’m very confused with all the problems and I desired to know how to resolve them.
