Merge branch 'arp-always-override-existing-neigh-entries-with-gratuitous-ARP'
Ihar Hrachyshka says:
====================
arp: always override existing neigh entries with gratuitous ARP
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.
