Subject: Re: [PATCH] arp_notify: unconditionally send gratuitous ARP for NETDEV_NOTIFY_PEERS.
Date: Mon, 14 Mar 2011 10:26:39 +0100 [thread overview]
Message-ID: <1300094799.30687.5.camel@seasc7941> (raw)
In-Reply-To: <20110215.105114.226760606.davem@davemloft.net>
Nice, so this is a generic way of getting out gratuitous arps.
Can it be used by drivers (macvlan) on top of bonding.
Bonding is sending the BOND_FAILOVER event that could be mapped
to NOTIFY_PEERS in the higher level devices.
And bonding is implementing its own grat arps functions, maybe it could
be broken out to use the NOTIFY_PEERS instead.
And what about IPv6, would it be ok to implement an unsolicited NA on
the event?
I will happily implement the above, if anyone thinks it's worth it?
