Ability to tweak the delay between gratuitous ND/ARP packets has been
added in kernel commit 07a4ddec3ce9 ("bonding: add an option to
specify a delay between peer notifications"), through
IFLA_BOND_PEER_NOTIF_DELAY attribute. Add support to set and show this
value.
Example:
$ ip -d link set bond0 type bond peer_notif_delay 1000
$ ip -d link l dev bond0
2: bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue
state UP mode DEFAULT group default qlen 1000
link/ether 50:54:33:00:00:01 brd ff:ff:ff:ff:ff:ff
bond mode active-backup active_slave eth0 miimon 100 updelay 0
downdelay 0 peer_notif_delay 1000 use_carrier 1 arp_interval 0
arp_validate none arp_all_targets any primary eth0
primary_reselect always fail_over_mac active xmit_hash_policy
layer2 resend_igmp 1 num_grat_arp 5 all_slaves_active 0 min_links
0 lp_interval 1 packets_per_slave 1 lacp_rate slow ad_select
stable tlb_dynamic_lb 1 addrgenmode eu
