Subject[PATCH net-next v3 0/9] forcedeth: stats & debug enhancements
Date
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 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
