Subject: Regarding Routing cache

Hi,

I have a small doubt regarding routing cache in linux kernel.

It seems ip_route_connect is the way we have to access routing cache
entries. In case of all locally generated packets I see that struct
dst_entry is filled up with a lookup in routing cache.

What about in case of forwarding packets ? I dont see any usage of
routing cache mechanism to fill up the struct dst_entry. So it seems
we directly check the fib_rules or fib table to fill the structure.
If it is true then it would be very slow right ?

Sorry if I am wrong about above findings. Do correct me if I am wrong about it ?

Regards,
Ajith
