These changes are intended for easier handling with IP addresses
(not have to calculate dad for IPv6 when adding IP address).
Add -a IP and -s options to tst_add_ipaddr()
tst_del_ipaddr() (which uses internally tst_add_ipaddr()) is defined
mainly for better code readability.

* Drop route command (use just ip command), support both IPv4 and IPv6
* Add route-lib.sh (will be used in other route-change-*)
* Use unused network range to avoid clash with real network
* Add verification with ping (previous version sent UDP datagram with
ns-udpsender, but didn't verify receiving it on rhost and didn't setup
rhost ip at all)

We should keep $(($1 + 1)) within the valid range except already added IP address
($lhost), i.e. for IPv4 the range is 2..254 for host id:
local gw="$(tst_ipaddr_un 1 $(($1 % 253 + 2)))"
Either we could limit the value here or in the tst_ipaddr_un(). Looks like
route-change-if needs a similar fix for net id?

May be it would be cleaner to use "add" instead of "replace" since we remove it
and it shouldn't exist before a test start.

It is better to redirect stdout to null:
EXPECT_PASS ping$TST_IPV6 -c1 -I $lhost $rhost \>/dev/null
The same for *-if and *-dst.
The rest in the patch-set looks good to me.

Good point (sorry to keep octet/hextet overflow related errors).
Although it'd be simpler to fix it in the code, I'd prefer to have this support
in tst_ipaddr_un(). Diff below adds -l MIN_HOST_ID (I'll post it as a part of v3),
do we want to lower also max host id?

It can only be "max host id" option since we already have this variable in the
function, and in the test setup, we could assign "lhost" variable with the max
value:
lhost="$(tst_ipaddr_un 1 $max_host_id)"

I'll have to implement min value as well, because we have for non-counter mode
(e.g tst_ipaddr_un $net_id $host_id) 0 as well, so it will break for invalid
gateway 10.23.1.0. I wanted to avoid -c mode for these route tests.
I guess <0-254> for max host ID for this mode was good idea, but IMHO it should
be: <0-255> (to allow both network address and broadcast address), and allow to
have minimize both min and max. So for case of valid address it'd would be:
tst_ipaddr_un -l 1 -m 254 $net_id $host_id
Other could be to have range for this mode default suitable for hosts (<1..254>)
as we have it for -c mode. Getting network would be:
tst_ipaddr_un -n $net_id # instead of tst_ipaddr_un $net_id 0
Getting broadcast would be:
tst_ipaddr_un -b $net_id # currently not possible at all with tst_ipaddr_un
This second proposal looks more usable to me, although -b and -n aren't obvious
(long getopts would be better, but I think it's better to avoid them).
+ I'd still keep proposed -m max_host_id, so we could use tst_ipaddr_un $net_id 254
for route and tst_ipaddr_un -m 253 $net_id $1 for hosts.
Kind regards,
Petr

* Drop route command (use just ip command), support both IPv4 and IPv6
* Use unused network range to avoid clash with real network
* Add verification with ping (previous version sent UDP datagram with
ns-udpsender, but didn't verify receiving it on rhost and didn't setup
rhost ip at all)
* Add tst_get_ifaces_cnt() into tst_net.sh

I guess I shouldn't add tst_get_ifaces_cnt() to tst_net.sh, if nothing
else uses it. I can move it to route-change-if.
