The callback allows to enable/disable multicast snooping.
When the snooping is enabled, all IGMP and MLD frames are redirected to
the CPU, therefore make sure not to set the skb flag 'offload_fwd_mark'.
The HW will not flood multicast ipv4/ipv6 data frames.
When the snooping is disabled, the HW will flood IGMP, MLD and multicast
ipv4/ipv6 frames according to the mcast_flood flag.

The blamed commit changed the vlan used by the host ports to be 4095
instead of 0.
Because of this change the following issues are seen:
- when the port is probed first it was adding an entry in the MAC table
with the wrong vlan (port->pvid which is default 0) and not HOST_PVID
- when the port is removed from a bridge, it was using the wrong vlan to
add entries in the MAC table. It was using the old PVID and not the
HOST_PVID
This patch fixes this two issues by using the HOST_PVID instead of
port->pvid.

Since commit 94dd016ae5 ("bond: pass get_ts_info and SIOC[SG]HWTSTAMP

PHC index directly. But when there is a failover, the bond active
interface will change, thus the PHC index is also changed. This may
break the user's program if they did not update the PHC timely.
This patch adds a new hwtstamp_config flag HWTSTAMP_FLAG_BONDED_PHC_INDEX.
When the user wants to get the bond active interface's PHC, they need to
add this flag and be aware the PHC index may be changed.
With the new flag. All flag checks in current drivers are removed. Only
