Harald Welte ebe0bbf06c [NETFILTER] nfnetlink: use highest bit of nfa_type to indicate nested TLV ... As Henrik Nordstrom pointed out, all our efforts with "split endian" (i.e. host byte order tags, net byte order values) are useless, unless a parser can determine whether an attribute is nested or not. This patch steals the highest bit of nfattr.nfa_type to indicate whether the data payload contains a nested nfattr (1) or not (0). This will break userspace compatibility, but luckily no kernel with nfnetlink was released so far. Signed-off-by: Harald Welte <laforge@netfilter.org> Signed-off-by: David S.
