Subject: payload: don't resolve expressions using the inet pseudoheader
X-Git-Tag: v0.8.3~25
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=d3b6a35d20040e62b1d88aeedccbe2184f06408e;p=thirdparty%2Fnftables.git

payload: don't resolve expressions using the inet pseudoheader

Else, '@ll,0,8' will be mapped to 'inet nfproto', but thats
not correct (inet is a pseudo header).
