Subject: [vpp-dev] more than 65K entries in a FIB table
Hi,
the FIB table implements two reference counters:
/**
* per-source number of locks on the table
*/
u16 *ft_locks;
u32 ft_total_locks;
While trying to add lots of GTP-U tunnels, which creates a new interface for
each tunnel in a FIB table, we have reached the u16 limit very fast. Our
requirement would be in the million range.
Would you be against of changing the per-source ft_locks to u32?
It increases the memory footprint, but I can hardly imagine having hundreds of
thousands of FIB tables. Adding that many entries into a single, or few FIB
tables is a valid case though.
If you agree, I can create a pull request.
Thanks,
Miklos
