Subject: [RFC PATCH 0/2] Improve tracing at the driver/core boundary

These patches add static tracpeoints at the driver/core boundary which
record various skb fields likely to be useful for datapath debugging.
On the TX side the boundary is where the core calls ndo_start_xmit, and
on the RX side it is where any of the various exported receive functions
is called.

The set of skb fields is mostly based on what I thought would be
interesting for sfc, and may need to be augmented to be more general.

Ben.

Ben Hutchings (2):
  net: Add net_dev_start_xmit trace event, exposing more skb fields
  net: Add trace events for all receive entry points, exposing more skb
    fields
