[PATCH net-next v1 0/9] forcedeth: stats & debug enhancements

[David Decotigny <david.decotigny@google.com>]

These changes implement the ndo_get_stats64 API and add a few more
stats and debugging features for forcedeth. They also ensure that
stats updates are correct in SMP systems, 32 or 64-bits.

Regarding the "implement ndo_get_stats64() API" patch, I'm not sure
I'm using the right way to protect the 64b stats. Ideally, I would
like them to be non-blocking (u64_stats_sync.h), but as there are
several sources for updates, I don't think I can do without locking or
per-CPU stats. Would per-CPU stats be better here (note: I expect the
contention on netdev_priv(dev)->stats_lock to be _VERY_ low)?

Tested:
  ~150Mbps incoming TCP, ethtool -S in a loop, x86_64 16-way:
     tx_bytes: 1413863329
     rx_packets: 38918872
     tx_packets: 19828148
     rx_bytes: 57818685991
