It's been in from at least Kilo (give or take a some bugfixes, it seems,
all of which deserve backporting).
It never worked as you would expect, though indeed a lot of code to
calculate MTU was
I like larger MTUs, and used to call stateless offloads like TSO/GSO
"Poor man's Jumbo Frames" but if you can get the stateless offloads
going, you can go beyond the savings one gets from JumboFrames because a
TSO/GSO/GRO "segment" can end-up being semi-effectively 32-64KB.

In the environment of openstack kilo, I test the bandwidth in the scene which

bandwidth. Is this a bug or any else issue, or is there some hotfix to solve
the issue? Thank you for answering!
