[PATCH net-next v4 0/8] forcedeth: stats & debug enhancements

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.

Changes since v3:
  - updated get_stats64 + rx_dropped patches to use u64_stats_sync.h
  - dropped indentation "whitespace/indentation fixes" (included in
    get_stats64 api patch)

Changes since v2:
  - patch 1/9 is the cherry-pick of 898bdf2cb43e ("forcedeth: fix
    stats on hardware without extended stats support")
  - removed patch 5/10 "stats for rx_packets based on hardware
    registers" because packets&bytes stats are updated in software
    only (898bdf2cb43e)

Changes since v1:
  - patch 1/10 is the same as
    http://patchwork.ozlabs.org/patch/125017/ (targetting net)
  - other patches updated to take patch 1/10 into account
  - various commit message updates


Tested:
  ~150Mbps incoming TCP, ethtool -S in a loop, x86_64 16-way:
     tx_bytes: 5441989419
     rx_packets: 5439224
     tx_timeout: 0
     tx_packets: 5456705
     rx_bytes: 5566763850

Tested:
  pktgen + loopback report same RX/TX packets and bytes stats

Tested:
  tests above with Kconfig DEBUG_PAGEALLOC DEBUG_MUTEXES
  DEBUG_SPINLOCK LOCKUP_DETECTOR DEBUG_RT_MUTEXES DEBUG_LOCK_ALLOC
  PROVE_LOCKING DEBUG_ATOMIC_SLEEP DEBUG_STACK_USAGE DEBUG_KOBJECT
  DEBUG_VM DEBUG_LIST DEBUG_SG DEBUG_NOTIFIERS TEST_KSTRTOX
  STRICT_DEVMEM DEBUG_STACKOVERFLOW
