Off the topic.

This is the patch 100.000 in patchwork! Wow, that is huge.

This may be something to celebrate on next face to face meeting.
And I assume Bruce will be buying as the owner of the patch 100000 :)

The historical numbers from DPDK patchwork:
100000 - Sept. 29, 2021 (184 days) [ 6 months / 26 weeks and 2 days ]
  90000 - March 29, 2021 (172 days)
  80000 - Oct.   8, 2020 (153 days)
  70000 - May    8, 2020 (224 days)
  60000 - Sept. 27, 2019 (248 days)
  50000 - Jan.  22, 2019 (253 days)
  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

Last two years average is 10K patch in ~185 days, that is more patch per day
comparing to previous years.
Not sure if this is Covid-19 effect or simply DPDK is getting more popular.

Thanks again to all contributors.
