Subject: [PATCH 4.4 stable 00/10] net: ip6 defrag: backport fixes 

This is a backport of a 5.1rc patchset:
  https://patchwork.ozlabs.org/cover/1029418/

Which was backported into 4.19:
  https://patchwork.ozlabs.org/cover/1081619/

and into 4.14:
  https://patchwork.ozlabs.org/cover/1089651/

and into 4.9:
  https://www.spinics.net/lists/netdev/msg567087.html 

This patchset for 4.4 is based on Peter Oskolkov's patchsets above.
5 additional patches has been added to make it all apply, build
and pass TAHI IPv6 Ready test with the IOL INTACT test tool.
Without this patchset 2 extension header tests and 12 fragmentation
tests fail to pass. The previous attempt to fix this seamed to end
here: https://www.spinics.net/lists/netdev/msg567728.html
It would be nice if someone with more netfilter
and fragmentation knowledge than me could review it.
