[NETNS][IPV6] ip6_fib - add net to gc timer parameter
The fib tables are now relative to the network namespace. When the garbage collector timer expires, we must have a network namespace parameter in order to retrieve the tables. For now this is the init_net, but we should be able to have a timer per namespace and use the timer callback parameter to pass the network namespace from the expired timer. The timer callback, fib6_run_gc, is actually used to be called synchronously by some functions and asynchronously when the timer expires. When the timer expires, the delay specified for fib6_run_gc parameter is always zero. So, I changed fib6_run_gc to not be a timer callback but a function called by the timer callback and I added a timer callback where its work is just to retrieve from the data arg of the timer the network namespace and call fib6_run_gc with zero expiring time and the network namespace parameters. That makes the code cleaner for the fib6_run_gc callers. Signed-off-by: Daniel Lezcano <dlezcano@fr.ibm.com> Signed-off-by: Benjamin Thery <benjamin.thery@bull.net> Signed-off-by: David S.
