Hi, This patchset recovers the initial effort from Jeremy Sowden to enhance mark statement support for variable expression, eg. use an existing selector to set the meta and ct mark. This also includes support for bitwise arithmetics, including shift operations. Selectors in network byte order are turned into host byte order before the assignment to ensure ruleset portability. No kernel updates are required in this batch. Patches 1 to 5 are preparation work for patch 5, which finally adds support for mark statements compatibility with selectors using integer basetype: Patch #1 provides a fix for missing byteorder conversion in network byteorder field between 9 and 15 bytes such as ip6 dscp. Patch #2 prepares for listing bitwise expression in hexadecimal, instead of using symbolic values specific of the datatype of the expression. Patch #3 upgrade length of shift to the mark statement size, to allow for larger shift than the expression length. Patch #4 remove redundant evaluation of unary expression arguments. Patch #5 use length of mark statements for the bitwise expression, instead of the length of the r-value expression. Finally patch #6 allows for datatype compatibility between mark statements and rvalue expression of integer datatype. This includes byteorder compatibility conversion. Patch 7 to 9 add more tests.
