In CentOS7(iputils-20160308-10.el7.x86_64), udpgro_fwd.sh output
following message:
ping: 2001:db8:1::100: Address family for hostname not supported
Use ping6 on systems where ping doesn't handle IPv6.
v1 -> v2:
- explicitly checking the available ping feature, as e.g. do the
bareudp.sh self-tests.(Paolo)
Fixes: a062260a9d5f ("selftests: net: add UDP GRO forwarding self-tests")

I'm afraid v1 got silently applied, see 8b3170e07539 ("selftests: net:
using ping6 for IPv6 in udpgro_fwd.sh") upstream. Could you send an
incremental patch?
