Hey Christian,

 Nice job on fixing many DPDK package bugs!   :-D

Sounds perfect! I'm there now, "tmartins" nick...

That would be awesome!

Verified, it is working now.

After latest release on Xenial, it looks very good! Both UIO and VFIO works
without effort.

I can easily switch between UIO and VFIO, that DPDK shows the NICs being
used as "DPDK-Compatible drivers".

Only OpenvSwitch+DPDK doesn't see any "dpdk0 | dpdk1" devices but, I know
you guys are working into this...

Sounds great!

That sounds like a good plan, I totally understand that...   =)

You can count on me! I'm a big fan of Ubuntu...

I met Mark in Vancouver on OpenStack summit, he is a great guy and it is
easier now to see why Ubuntu is so cool! A lot of amazing people working
here!     ^_^

So I wanted to ask if you could be patient for a few days, once my Env is

Of course! I'll be the beta tester.    ;-)

Just for the record, we moved this thread to Ubuntu Server, here is the
previous thread on Ubuntu Devel, so, people on Ubuntu Server will
understand what we're talking about:
