Re: DPDK supported processor

[BYEONG-GI KIM <kimbyeonggi-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

Hello.

Hmm, the problem is a little complicated. Actually, I'm trying to use
dpdk-ovs with openstack deployment, but it seems not working correctly.
I've thus been trying to keep track of the primary problem of this.

I've thought my machine's hardware requirements may not be satisfied to
support DPDK, but I think it is solved now.

Best regards
