[dpdk-ci] June 17 Community CI Meeting Minutes

[Lincoln Lavoie]

Hi Zhaoyan,

Owen from our team has been leading the efforts on getting ASAN running on
(under, with) DPDK.  He's got a couple of patches submitted fixing some
smaller issues he's seen.  I think David Marchand also had some patches
started to fix some of the issues as well.

Cheers,
Lincoln
