[nft,v2,0/8] mark statement support for non-constant expression

Hi,

This is v2 of the following patchset:

https://marc.info/?l=netfilter-devel&m=167904710124404&w=2

this takes over the initial effort from Jeremy Sowden to enhance mark
statements support for variable expression.

No kernel updates are required in this batch.

Previous patch #1 in this series has been already applied upstream:

fe623a509492 ("evaluate: insert byte-order conversions for expressions between 9 and 15 bits")

Main change is patch #2 in this series:

("evaluate: support shifts larger than the width of the left operand")

which slightly simplifies the logic to set the maximum shift length
according to the mark statement datatype length (which is 32-bits).

Anything else, no changes.

Jeremy Sowden (4):
  netlink_delinearize: correct type and byte-order of shifts
  evaluate: don't eval unary arguments
  tests: shell: rename and move bitwise test-cases
  tests: shell: add test-cases for ct and packet mark payload expressions

Pablo Neira Ayuso (4):
  evaluate: support shifts larger than the width of the left operand
  evaluate: get length from statement instead of lhs expression
  evaluate: relax type-checking for integer arguments in mark statements
  tests: py: add test-cases for ct and packet mark payload expressions
