Milestone: 4.1
Deprecates: VLAN splinters usage
Depends-on: bound removal between kmod-openvswitch and openvswitch packages, nailgun kernel selection passthrough

How does this depercrate vlan splinters?

[xdel]

This exact commit does not deprecate them but usage of 3.10+ kernel does - it will be replacement for current splinters-inavoidable cases. We will have no overhead for any imaginable vlan ranges and slightly broader HCL paying by kABI breakage. Old 2.6.32 will remain as a default selection of course.

At least one user has indicated that the 3.10 kernel causes panic's on their hardware (Slightly Older HP Blade) Moving to fedora kernel Isn't a good option for everyone. This also indicates that further hardware testing must be done prior to accepting the new kernel

[xdel]

It should not be default selection but only for models having unbeatable issue with connectivity in VLAN isolation mode.
