src: Support odd-sized payload matches
When expanding a payload match, don't disregard oversized templates at the right offset. A more flexible user may extract less bytes from the packet if only parts of a field are interesting, e.g. only the prefix of source/destination address. Support that by using the template, but fix the length. Later when creating a relational expression for it, detect the unusually small payload expression length and turn the RHS value into a prefix expression. Signed-off-by: Phil Sutter <>
