Subject: ip_forward notification for driver

Hello.

I'm working on L3 routing offload for switch device and have a
question about ip_forwarding. I want to disable/enable forwarding on
the hardware side according to changing value in
/proc/sys/net/ipv4/ip_forward. As I see, inet_netconf_notify_devconf
just sends rtnl_notify for userspace. Could I ask you for advice, on
how can I handle updating value via some notifier or some other Linux
mechanism in driver?

Thank you in advance.

Kind Regards, Leonid.
