ice: add remaining migration TLVs
Add a handful of remaining TLVs to complete the migration payload data
including:
* ICE_MIG_TLV_MBX_REGS
This TLV contains the VF mailbox registers data to migrate and restore
the mailbox queue to its appropriate state.
* ICE_MIG_TLV_STATS
This TLV contains the VF statistics to ensure that the original and
target VM maintain the same stat counts.
* ICE_MIG_TLV_RSS
This TLV contains the RSS information from the original host, ensuring
that such configuration is applied on the new host.
* ICE_MIG_TLV_VLAN_FILTERS
This TLV contains all the VLAN filters currently programmed into
hardware by the VF. It is sent as a single variable length flexible
array instead of as individual TLVs per VLAN to avoid a 4-byte overhead
per-VLAN.
* ICE_MIG_TLV_MAC_FILTERS
This TLV contains all of the MAC filters currently programmed into the
hardware by the VF. As with VLANs, it is sent as a flexible array to
avoid too much overhead when there are many filters.
Add functions to save and restore this data appropriately during the live
migration process.
