I think your patchset introduces a regression bug. If we created
multiple IPoIB VLAN interfaces, the TCP/IP network will be impacted.
1) Upstream kernel-4.12.0-rc2.409dcf31538a, can't control IPoIB VLAN
interface over ifdown/ifup. ifup/ifdown over bare IPoIB interface works.
System Ethernet card can get DHCP IP address and up as expected.
2) Upstream kernel-4.14.0.0c86a6bd85ff, the TCP/IP network does not
work at all, as all IP interfaces, which include Ethernet interface and
IPoIB/VLAN interfaces, will failed to be initialized.
Issue can be reproduced with mlx4/mlx5/qib hardware. IPoIB works
when selinux disabled.
Please see attachment for details.
thanks
