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_notify_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_notify_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

There is a couple of places where we report error in case of no network
device is found. In all of them we output message in the same format to
stderr and either return -1 or 1 to the caller or exit with -1.
Introduce new helper function nodev() that takes name of the network
device caused error and returns -1 to it's caller. Either call exit()
or return to the caller to preserve behaviour before change.
Use -nodev() in traffic control (tc) code to return 1.
Simplify expression for checking for argument being 0/NULL in @if
statement.

While benefit from using ll_name_to_index() with populated
cache can potentially be exploited only in few places
(e.g. bridge fdb/mdb/vlan show routines) there is another
advantage of ll_name_to_index() over plain if_nametoindex():
in case of if_nametoindex() failure ll_name_to_index()
will attempt to get index from common name in form "if%d"
that may be returned from ll_index_to_name().
This makes output from ip(8) coherent with it's input.
Note that most of the code already switched from plain
if_nametoindex() to ll_name_to_index() to cached variant.

There are two reasons for switching to cached variant:
1) ll_index_to_name() may return result from cache,
eliminating expensive ioctl() to the kernel.
Note that most of the code already switched from plain
if_indextoname() to ll_index_to_name() to cached variant
in print path because in most cases cache populated.
2) It always return name in the form "if%d", even if
entry is not in cache and ioctl() fails. This drops
"link_index" from JSON output.

Allow to print particular link type usage by:

Currently to print usage for some link type it is needed
to use the following way:
ip link { add | del | set } type TYPE help

Lookup function get_index() compares argument with table entries
only up to the length of the table entry so that if an entry
with lower index is a substring of a later one, earlier entry is
used even if the argument is equal to the other. For example,
ip link set bond0 type bond xmit_hash_policy layer2+3
sets xmit_hash_policy to 0 (layer2) as this is found before
"layer2+3" can be checked.
Use strcmp() to compare whole strings instead.
