Log Message:
Introduce deferred if_start framework
The framework provides a means to schedule if_start that will be executed
in softint later. It intends to be used to avoid calling if_start,
especially bpf_mtap, in hardware interrupt.
It adds a dedicated softint to a driver if the driver requests to use the
framework via if_deferred_start_init. The driver can schedule deferred
if_start by if_schedule_deferred_start.
Proposed and discussed on tech-kern and tech-net
