The network device operation for reading statistics is only called
in one place, and it ignores the return value. Having a structure
return value is potentially confusing because some future driver could
incorrectly assume that the return value was used.

Fix all drivers with ndo_get_stats64 to have a void function.

Forcedeth currently uses disable_irq_lockdep and enable_irq_lockdep, which in

local_irq_save, leading to the following warning:

In order to enable lockdep on seqcount/seqlock structures, we
must explicitly initialize any locks.

The u64_stats_sync structure, uses a seqcount, and thus we need
to introduce a u64_stats_init() function and use it to initialize
the structure.

This unfortunately adds a lot of fairly trivial initialization code
to a number of drivers. But the benefit of ensuring correctness makes
this worth while.

Because these changes are required for lockdep to be enabled, and the
changes are quite trivial, I've not yet split this patch out into 30-some
separate patches, as I figured it would be better to get the various
maintainers thoughts on how to best merge this change along with
the seqcount lockdep enablement.

Feedback would be appreciated!

This complements patch "net-forcedeth: fix TX timeout caused by TX
pause on down link" which ensures that a lock-up sequence is not sent
to the NIC. Present patch ensures that if a NIC is already locked-up,
the driver will recover from it when initializing the device.

It does the equivalent of the following recovery sequence:
 - write NVREG_TX_PAUSEFRAME_ENABLE_V1 to eth1's register
   NvRegTxPauseFrame
 - write NVREG_XMITCTL_START to eth1's register
   NvRegTransmitterControl
 - write 0 to eth1's register NvRegTransmitterControl
(this is at the heart of the "unbricking" sequence mentioned in patch
 "net-forcedeth: fix TX timeout caused by TX pause on down link")

Tested:
 - hardware is MCP55 device id 10de:0373 (rev a3), dual-port
 - reboot a kernel without any of patches mentioned
 - freeze the NIC (details on description for commit "net-forcedeth:
   fix TX timeout caused by TX pause on down link")
 - wait 5mn until ping hangs & TX timeout in dmesg
 - reboot on kernel with present patch
 - host is immediatly operational, no TX timeout

On some dual-port forcedeth devices such as MCP55 10de:0373 (rev a3),
when autoneg & TX pause are enabled while port is connected but
interface is down, the NIC will eventually freeze (TX timeouts,
network unreachable).

This patch ensures that TX pause is not configured in hardware when
interface is down. The TX pause request will be honored when interface
is later configured.

Tested:
 - hardware is MCP55 device id 10de:0373 (rev a3), dual-port
 - eth0 connected and UP, eth1 connected but DOWN
 - without this patch, following sequence would brick NIC:
      ifconfig eth0 down
      ifconfig eth1 up
      ifconfig eth1 down
      ethtool -A eth1 autoneg off rx on tx off
      ifconfig eth1 up
      ifconfig eth1 down
      ethtool -A eth1 autoneg on rx on tx on
      ifconfig eth1 up
      ifconfig eth1 down
      ifup eth0
      sleep 120  # or longer
      ethtool eth1
   Just in case, sequence to un-brick:
      ifconfig eth0 down
      ethtool -A eth1 autoneg off rx on tx off
      ifconfig eth1 up
      ifconfig eth1 down
      ifup eth0
 - with this patch: no TX timeout after "bricking" sequence above

Details:
 - The following register accesses have been identified as the ones
   causing the NIC to freeze in "bricking" sequence above:
    - write NVREG_TX_PAUSEFRAME_ENABLE_V1 to eth1's register NvRegTxPauseFrame
    - write NVREG_MISC1_PAUSE_TX | NVREG_MISC1_FORCE to eth1's register NvRegMisc1
    - write 0 to eth1's register NvRegTransmitterControl
   This is what this patch avoids.

Use eth_hw_addr_random() instead of calling random_ether_addr()
to set addr_assign_type correctly to NET_ADDR_RANDOM.

Reset the state to NET_ADDR_PERM as soon as the MAC get
changed via .ndo_set_mac_address.

v2: adapt to renamed eth_hw_addr_random()
