Off the topic.

This is the patch 50000 in patchwork! This is a big number.
Thanks everyone contributed!

https://patches.dpdk.org/patch/50000/

The historical numbers from DPDK patchwork:
50000 - Jan. 22, 2019 (253 days) [ 8 months, 8 days / 36 weeks and 1 day ]
40000 - May. 14, 2018 (217 days)
30000 - Oct. 9, 2017 (258 days)
20000 - Jan. 25, 2017 (372 days)
10000 - Jan. 20, 2016 (645 days)
00001 - April 16, 2014


This is the first time DPDK patch pace slowed down (slightly), I guess this is
because of the holidays in the middle and small 19.02, but I think next
milestone which includes 19.05 will clarify this.
