[PATCH 0/2] arp: always override existing neigh entries with gratuitous ARP

[Ihar Hrachyshka <ihrachys@redhat.com>]

Good day.

This patchset is spurred by discussion started at
https://patchwork.ozlabs.org/patch/760372/ where we figured that there is no
real reason for enforcing override by gratuitous ARP packets only when
arp_accept is 1. Same should happen when it's 0 (the default value).

The first patch in the series moves is_garp code into a separate function
preparing the code base for the 2nd patch that actually implements the needed
change.

Ihar Hrachyshka (2):
  arp: decompose is_garp logic into a separate function
  arp: always override existing neigh entries with gratuitous ARP
