net/ifc: add LM mode parameter
This patch series enables a new method for live migration, i.e. software
assisted live migration. This patch provides a device argument for user
to choose the methold.
When "sw-live-migration=1", driver/device will do live migration with a
relay thread dealing with dirty page logging. Without this parameter,
device will do dirty page logging and there's no relay thread consuming
CPU resource.
