hw addr for ip addr from user space (iwspy,arp)?

[Dan Forsberg]

Hi,

I'm using iwspy to monitor the quality of the link. SIOCSIWSPY needs
ethernet addresses. If there isn't arp cache entry for the ip address then
it doesn't work. Now, my question is how to get the arp entry into the
cache for a specific ip address? I don't want to send any unnecessary
packets (icmp echo etc.). Is there a way to send arp queries from a user
space daemon and get the result in kernels arp cache? Some sort of
interface into the kernel? 

Cheers,
