    net/tc: introduce TC_ACT_REINSERT. · cd11b164
    Paolo Abeni authored
    This is similar TC_ACT_REDIRECT, but with a slightly different
    semantic:
    - on ingress the mirred skbs are passed to the target device
    network stack without any additional check not scrubbing.
    - the rcu-protected stats provided via the tcf_result struct
      are updated on error conditions.
    
    This new tcfa_action value is not exposed to the user-space
    and can be used only internally by clsact.
    
    v1 -> v2: do not touch TC_ACT_REDIRECT code path, introduce
     a new action type instead
    v2 -> v3:
     - rename the new action value TC_ACT_REINJECT, update the
       helper accordingly
     - take care of uncloned reinjected packets in XDP generic
       hook
    v3 -> v4:
     - renamed again the new action value (JiriP)
    v4 -> v5:
     - fix build error with !NET_CLS_ACT (kbuild bot)
