MoCA interfaces require the use of an user-space daemon (mocad) which
will typically use cmd->autoneg to force the link. This is causing other
network manager applications not to get proper carrier down
notifications because of the following sequence of events:

- link down interrupt is received, link is set to 0 by the interrupt
  handler
- fixed_link update callback runs and updates the BMSR register
  accordingly
- PHY library polls the PHY for link status, sees the link is down,
  proceeds with reporting that
- mocad gets notified of the link state and call phy_ethtool_sset()
  with cmd->autoneg set to the link status (0)
- phy_start_aneg() is called at the end of phy_ethtool_sset() and sets
  the PHY state to PHY_FORCING

Just make sure we notify the interface carrier appropriately when we
detect that the link is down in our fixed_link update callback. This is
made local to the bcm_sf2 driver as the PHY library does the right thing
in any case. This is similar to the GENET change introduced in
54d7c01d ("net: bcmgenet: enable MoCA
link state change detection").

Currently the struct netvsc_stats has a member s_sync
of type u64_stats_sync.
This definition will break kernel build as the macro
netdev_alloc_pcpu_stats requires this member name to be syncp.
(see netdev_alloc_pcpu_stats definition in ./include/linux/netdevice.h)

This patch changes netvsc_stats's member name from s_sync to syncp to fix
the build break.

Once we get a neighbour through looking up arp cache or creating a

already taken. But as we don't put the refcount again after it's
used, this makes the neighbour entry leaked.

Current code does not lock anything when calculating the TX and RX stats.
As a result, the RX and TX data reported by ifconfig are not accuracy in a
system with high network throughput and multiple CPUs (in my test,
RX/TX = 83% between 2 HyperV VM nodes which have 8 vCPUs and 40G Ethernet).

This patch fixed the above issue by using per_cpu stats.
netvsc_get_stats64() summarizes TX and RX data by iterating over all CPUs
to get their respective stats.

This v2 patch addressed David's comments on the cleanup path when
netdev_alloc_pcpu_stats() failed.

OS2BMC feature will allow the server to communicate with the on-board
BMC/idrac (Baseboard Management Controller) over the LOM via
standard Ethernet.

When OS2BMC feature is enabled, the LOM will filter traffic coming
from the host. If the destination MAC address matches the iDRAC MAC
address, it will forward the packet to the NC-SI side band interface
for iDRAC processing. Otherwise, it would send it out on the wire to
the external network. Broadcast and multicast packets are sent on the
side-band NC-SI channel and on the wire as well. Some of the packet
filters are not supported in the NIC and hence driver will identify
such packets and will hint the NIC to send those packets to the BMC.
This is done by duplicating packets on the management ring. Packets
are sent to the management ring, by setting mgmt bit in the wrb header.
The NIC will forward the packets on the management ring to the BMC
through the side-band NC-SI channel.
