intel82599开启sr-iov直通vf给爱快无法用vlan拨号

fishensl

我搜的国外intel 论坛反馈的，别x710也是实体机通过vlan不通虚机，intel答复是要禁用vlan tag stripping，但是老哥禁用了也还是一样不通。。。后来他发现了一个bug。。。


I found a way to get the VLAN tag.

I need to set a VLAN on the VF and remove it:

[root@SLI-SRV3 images]# ip link set eno1 vf 1 vlan 10

[root@SLI-SRV3 images]# ip link set eno1 vf 1 vlan 0

[root@SLI-SRV3 images]#

It looks like a bug in the driver.

这么看按照intel的说法默认vlan 剥离是开启的，所以不通，要禁用 vlan tag stripping 才行，可能其他系统已经做了这个操作但是爱快因为不是原生支持可能是默认剥离vlan tag了。
