ping6 is needed for some tst_net.sh based tests (and for
netns_helper.sh, but it handles the dependency itself).
iputils commit ebad35f ("ping: merge `ping6` command into `ping`") [1],
released in s20150815 stopped providing ping6 and left it on
distributions (see also [2]).
Some distros don't create it (or didn't create it in the past [3]),
use workaround and warn about it (as it's also a bug which should
be fixed).
NOTE: Unfortunately we cannot use 'ping -${TST_IPVER}' as ping got '-6'
switch (as a part of support for IPv6) was in commit 25aaaf4 ("Allow ping
to use IPv6 addresses") [4], released in s20150815 (previous versions
supported only ping6).

Hi Alexey,
used a bit strange syntax, but it handles aliases.
Kind regards,
Petr

What about printing the message on the first usage only?
if [ -z "$ping6_warn_printed" ]; then
tst_res_ TINFO "ping6 ..."
ping6_warn_printed=yes
fi

The rest looks good.

Make sense. Added with export (required to be working properly).

Applied with your ack-by and suggested-by
