Subject: [RFC PATCH] extend RTM_GETNEIGH to allow getting more precise information

Hello.

Please have a look at this patch which tries to solve a problem we 
encountered.

The background is that RTM_GETNEIGH netlink message is used to get a complete 
dump of a neighbor table. Sometimes, that's too much (especially when you have 
a lot of neighbors). This patch allows one to specify the IPv4/6 address of a 
neighbor and the device index through which it is accessible in order to 
obtain only that entry.

If you have other suggestions on how to accomplish this task, please let us 
know.

Thanks,
Cosmin.
