commit b422b07ab2f96436001f33dfdfd937238033c799
("src: permit use of constant values in set lookup keys") allows to do
something like this:
set s { type ipv4_addr . ipv4_addr . inet_service .. } something
add rule ip saddr . 1.2.3.4 . 80 @s goto c1
However, it turns out that this only works if the constant(s)
(1.2.3.4 and 80) have BYTEORDER_BIG_ENDIAN type.
Combining a fixed value with a key portion of HOST type results in
a crash (assertion).
First patch is a refactor, second patch adds needed byteorder
conversions to deal with this problem.
