[Qemu-devel] [PULL 06/17] slirp: Generalizing and neutralizing ARP code

[Jason Wang <jasowang@redhat.com>]

From: Guillaume Subiron <maethor@subiron.org>

Basically, this patch replaces "arp" by "resolution" every time "arp"
means "mac resolution" and not specifically ARP.

This prepares for IPv6 support.
