[NETFILTER] ctnetlink: add one nesting level for TCP state
To keep consistency, the TCP private protocol information is nested attributes under CTA_PROTOINFO_TCP. This way the sequence of attributes to access the TCP state information looks like here below: CTA_PROTOINFO CTA_PROTOINFO_TCP CTA_PROTOINFO_TCP_STATE instead of: CTA_PROTOINFO CTA_PROTOINFO_TCP_STATE Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> Signed-off-by: Harald Welte <laforge@netfilter.org> Signed-off-by: David S. Miller <davem@davemloft.net>
