Question about the email about "[PATCH 2/3] IPV6: unify 3 similar code path in ndisc_recv_ns()"
Subsystems (2)
Dear David S. Miller :
Happy to write to you.
In the email <[email protected] >
<http://oss.sgi.com/archives/netdev/2004-02/msg00111.html>>,
yoshfuji unified 3 similar code patch in ndisc_recv_ns(). I have a question about the "flags sent with NA in reply to this NS" . In the kernel 2.4.21, it is as follows:
ndisc_send_na(dev, neigh, saddr,
&msg->target,
idev->cnf.forwarding, 1, 0, inc);
in you patch it is as follows:
ndisc_send_na(dev, neigh, saddr, &msg->target,
idev->cnf.forwarding,
1, (ifp != NULL && inc), inc);Can you tell me why you modified the flag O(override)? Thanks a lot!
