When counting "Instructions Retired" (0xc0) in a guest, KVM will
occasionally increment the PMU counter regardless of if that event is
being filtered. This is because some PMU events are incremented via
kvm_pmu_trigger_event(), which doesn't know about the event filter. Add
the event filter to kvm_pmu_trigger_event(), so events that are
disallowed do not increment their counters.

The VLAN filters info is currently being held in a list and 2 bitmaps
(active_cvlans and active_svlans). We are experiencing some racing where
data is not in sync in the list and bitmaps. For example, the VLAN is
initially added to the list but only when the PF replies, it is added to
the bitmap. If a user adds many V2 VLANS before the PF responds:
while [ $((i++)) ]
ip l add l eth0 name eth0.$i type vlan id $i
we might end up with more VLAN list entries than the designated limit.
Also, The "ip link show" will show more links added than the PF limit.
On the other and, the bitmaps are only used to check the number of VLAN
filters and to re-enable the filters when the interface goes from DOWN to
UP.
This patch gets rid of the bitmaps and uses the list only. To do that,
the states of the VLAN filter are modified:
1 - IAVF_VLAN_REMOVE: the entry needs to be totally removed after informing
the PF. This is the "ip link del eth0.$i" path.
2 - IAVF_VLAN_DISABLE: (new) the netdev went down. The filter needs to be
removed from the PF and then marked INACTIVE.
3 - IAVF_VLAN_INACTIVE: (new) no PF filter exists, but the user did not
delete the VLAN.

When arp_validate is set to 2, 3, or 6, validation is performed for
backup slaves as well. As stated in the bond documentation, validation
involves checking the broadcast ARP request sent out via the active
slave. This helps determine which slaves are more likely to function in
the event of an active slave failure.
However, when the target is an IPv6 address, the NS message sent from
the active interface is not checked on backup slaves. Additionally,
based on the bond_arp_rcv() rule b, we must reverse the saddr and daddr
when checking the NS message.
Note that when checking the NS message, the destination address is a
multicast address. Therefore, we must convert the target address to
solicited multicast in the bond_get_targets_ip6() function.
Prior to the fix, the backup slaves had a mii status of "down", but
after the fix, all of the slaves' mii status was updated to "UP".
