Subject: [V2 PATCH net-next 0/5] xdp: more work on xdp tracepoints

More work on streamlining the tracepoints for XDP.

I've created a simple xdp_monitor application that uses this
tracepoint, and prints statistics. Available at github:

https://github.com/netoptimizer/prototype-kernel/blob/master/kernel/samples/bpf/xdp_monitor_kern.c
https://github.com/netoptimizer/prototype-kernel/blob/master/kernel/samples/bpf/xdp_monitor_user.c

V2: Change trace_xdp_redirect() to align with args of trace_xdp_exception()

---

Jesper Dangaard Brouer (5):
      xdp: remove bpf_warn_invalid_xdp_redirect
      xdp: make generic xdp redirect use tracepoint trace_xdp_redirect
      ixgbe: use return codes from ndo_xdp_xmit that are distinguishable
      xdp: remove net_device names from xdp_redirect tracepoint
      xdp: get tracepoints xdp_exception and xdp_redirect in sync
