Those functions are part of the implementation of the lagg driver,
internal to the kernel. They generally mirror similarly-named functions
for all network drivers.
xxx_ioctl() is for processing ioctl() calls from userland
xxx_input() is for processing packets that arrive at the interface
xxx_start() is for processing packets that are outbound from the interface
xxx_create() for creating a new lagg interface
xxx_attach() for attaching a laggport to a lagg interface
and so on...
If you want to programmatically attach, configure, modify, destroy lagg
interfaces then you have choices like:
shell scripts
C code that performs the desired functions in the same way as ifconfig
(userland)
I can't see any immediate reason why you'd call functions like
lagg_input() directly and you would have to be kernel-side to do so.
What are you trying to achieve?
Hope this helps!
