[PATCH v2 0/4] arp: always override existing neigh entries with gratuitous ARP

[Ihar Hrachyshka <ihrachys@redhat.com>]

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).

changelog v2: handled review comments by Julian Anastasov
- fixed a mistake in a comment;
- postponed addr_type calculation to as late as possible.

Ihar Hrachyshka (4):
  arp: fixed error in a comment
  arp: decompose is_garp logic into a separate function
  arp: postpone addr_type calculation to as late as possible
  arp: always override existing neigh entries with gratuitous ARP
