The "-a" flag in Linux just changes the output format. I think you're thinking of the windows arp command, where the "/a" flag displays the whole table.

In any case, according to the strace command, linux ARP doesn't use ioctls to get the ARP table -- it slurps it in from the special file /proc/net/arp all in one big read. Try cat /proc/net/arp.
