retrieving the interface name via ip address

[e9hack]

Hi,

it exist the two functions network_get_subnet and network_get_subnet6 in /lib/functions/network.sh. They return the first ip or ip6 address of a given interface. In my case:

root at my-openwrt:~# . /lib/functions/network.sh; network_get_subnet subnet "lan"; echo $subnet; network_get_subnet6 subnet6 "lan"; echo $subnet6
192.168.107.1/24
fec0:0:0:eeee::1/64

Does exist the reverse function too? I would like to get the interface for an ip address, ether for the real address of the interface or for an ip address of the subnet.

Regards,
Hartmut
