This information is primarily gleaned from the top-level NEWS file.
For most of these, I did not verify them by looking carefully through
the history, so some of them may be inaccurate.

Hi, Ben.
Just trying to figure out from where these '2.7's came from for userspace
datapath.
For example, IIRC, 'NIC bonding' was there before 2.7.
Is there something I missed that makes this version so special?
This is really from conflating DPDK with the userspace datapath. 2.7
was when the "experimental" tag was removed from DPDK support. If we
ignore that (since the userspace datapath supported all of these
basically forever), we might as well just write the same as the kernel
datapath values there.
Hmm. I see.
Personally, I have never been a fan of equalization of "DPDK" and "Userspace
datapath".
And never liked words "DPDK datapath" as there is no such datapath in OVS.
Userspace datapath is agnostic to netdev types, so I'm not sure about versions
we should mention. BTW, there is no DPDK support on BSD in OVS, but userspace
datapath exists and functional.
BTW2, in this phrase:
+ given feature into the included kernel module or the userspace
+ (DPDK) datapath, respectively.
DPDK catches my eyes too.
I'm not sure how to make this right.
Best regards, Ilya Maximets.
