    IPVS: netns to services part 1 · fc723250

    Services hash tables got netns ptr a hash arg,
    While Real Servers (rs) has been moved to ipvs struct.
    Two new inline functions added to get net ptr from skb.
    
    Since ip_vs is called from different contexts there is two
    places to dig for the net ptr skb->dev or skb->sk
    this is handled in skb_net() and skb_sknet()
    
    Global functions, ip_vs_service_get() ip_vs_lookup_real_service()
    etc have got  struct net *net as first param.
    If possible get net ptr skb etc,
     - if not &init_net is used at this early stage of patching.
    
    ip_vs_ctl.c  procfs not ready for netns yet.

    - __ip_vs_service_find and __ip_vs_svc_fwm_find are fast path,
      net_eq(svc->net, net) so the check is at the end now.
    - net = skb_net(skb) in ip_vs_out moved after check for skb_dst.
