We upload only LTS releases to Debian/Ubuntu, so as long as those stay
the same as it is proposed here, no problem for us.

Someone else might comment if they spot something, but to me looks ok
for RH distro and OVS project.
RH distro is also using DPDK .11 who's release date is not changing.
(+cc Timothy/Flavio)
For OVS project, it only integrates DPDK .11 release too and aims to do
that by EOY to make the next OVS release. DPDK stable releases are
integrated into older OVS branches when available. I don't think older
OVS branch releases have a strict release schedule and having the latest
stable DPDK release is not a blocker anyway. (+cc Ilya/Ian/ovs-discuss)

That is my impression as well.

My concern is if patches would get delayed to be merged because of this
change, but I don't think that will be the case.

I agree that this schedule change doesn't change much for OVS.
One thing to highlight though: Change of main release schema
seems to directly impact schedule of stable releases.
In this case, interval between DPDK stable releases increases
from 3+ to 4+ months. This might be a long time to wait for
certain bug fixes, especially if OVS needs to skip one of the
DPDK stable releases due to issues introduced in it.
Anyway, doesn't sound like something critical to me.
Bets regards, Ilya Maximets.

This nicely adapts to the natural slowdown due to holidays
in December and August.

Atomic Rules has been releasing our Arkville product in lockstep with DPDK
for the past 19 quarters. Our FPGA solution has the added burden of testing
with async releases of FPGA vendor CAD tools. Although we have gotten used
to the quarterly cadence, for the reasons given by Thomas and others,
Atomic Rules supports the move to a three release per year schedule.
