Hi Nikhil, - Please re base to dpdk-next-eventdev - There is one check-git-long error. Please fix it Wrong headline lowercase: eventdev: add event type for eth rx adapter - You are planning to send the programmer guide with version. Right? Are planning to send now or post RC1 ? - For it looks OK to pull in next-eventdev, after fixing the http://dpdk.org/ml/archives/dev/2017-October/077915.html and exiting comments CC: Hemant Agrawal CC: Nipun Gupta Does any have any objection to pull this in RC1 if Nikhil sends the next version in time?
