[dpdk-stable] [PATCH 1/3] net/enic: fix flow API memory leak

[John Daley (johndale)]

Hi Yongseok,

It should go into 17.11 and hopefully 18.02, 18.05, 18.08 eventually.

Not sure what  you mean when you say it was only for stable releases. It was submitted to dev@ with the Cc: stable@ in the commit. The patch is here: https://patches.dpdk.org/patch/45545/

When cc'ing stable in dev@ submissions, should we generally follow up with an email to stable@ to indicate which stable branches to target? If so, should we update the instructions in the contributors guide (section 6.4), or did I miss where that process is documented?

Thanks,
John
