ipvs: move struct netns_ipvs
Remove include/net/netns/ip_vs.h because it depends on structures from include/net/ip_vs.h. As ipvs is pointer in struct net it is better to move struct netns_ipvs into include/net/ip_vs.h, so that we can easily use other structures in struct netns_ipvs. Signed-off-by: Julian Anastasov <ja@ssi.bg> Signed-off-by: Simon Horman <horms@verge.net.au>
